In 1906 Geiger Marsden and Rutherford scattered alpha-particles on a thin gold foil and determined the scattering angle from the light flash produced at the impact point of the alpha-particles on a phosphor screen The light detector was the human eye which has a remarkable sensitivity when it is adapted to the dark
In the year 1913 Elster and Geiter invented the photoelectric tube and in 1930 the first photomultiplier tube (PMT) was invented by L Kubetsky
In 1939 V Zworykin and his colleagues from the RCA laboratories developed a PMT with electrostatic focusing [3] the basic structure of current PMTrsquos and a short time after it became a commercial product Single photons were detectable from now on Further innovations have led to highly sophisticated devices available nowadays PMTrsquos have two severe handicaps they are very sensitive to magnetic fields (some devices tolerate axial magnetic fields) and their price is high because the complicated mechanical structure inside a vacuum container is mostly handmade

Signal from UHECR appears as a moving spot of light in focal plane It produced a track on the pixel network which is finishing by spot of Cherenkov light scattered and reflected by clouds
Signal track is resulting in a number of triggered pixels and recorded by pixel electronics in form of oscillogram
The amplitude and temporal characteristic of the signal give information about CR energy and coming direction
The presence of Cherenkov signal allows to measure absolute track depthLIDAR system is used to measure distance to the ldquoreflectiverdquo clouds and finding depth development of the signal in atmosphere

The crystal ball for the measurement of pibeta decay π+rarrπ0+e++ν followed by π0rarrγ+γ which has a branching ratio of 10-8 is made of 240 pure CsI crystals The crystal readout needs to cover the large area of the rear crystal face it has
to be very sensitive because the light yield of pure CsI is only few percent compared to NaI(Tl) and it has to be fast in order to allow an efficient
suppression of accidental coincidences The choice was a fast 10-stage PMT with 78 mm diameter from Electron Tubes The PMTrsquos have a quartz entrance window (emission wavelength of pure CsI is 315 nm) and are directly glued to
the crystals
The Muegamma experiment at PSI measure the decay μ+rarr e+γ with a sensitivity better than 5 10sdot 14 The γrsquos detected in a 800 l liquid xenon calorimeter by the observation of the scintillation light with 800 PMTrsquos The deposited energy derived from the sum of all PMT signals and the position of the γ conversion calculated from the distribution of the individual amplitudes

SOLID STATE DETECTORSThe main disadvantages which impede use PMT in some specific applications are large sizes the high voltage of power supply and sensitivity to the magnetic fields Furthermore during the construction of the systems which contain hundred thousand channels of registration important factor becomes the price of detector which in the case PMT is sufficiently highThese factors became the reason for the active development of the solid-state instruments which use a phenomenon of the photoconductive effect The semiconductor detectors of photons can be divided into two large groups the photodetectors in which the transformation of light signal occurs bullwithout the internal amplification of chargebull photodetectors with the internal amplification of charge The first group includes the p-i-n photodiodes which because of their reliability compactness and low cost successfully adapt in different physical experimentsThe quantum effectiveness of these photodiodes in the maximum of spectral sensitivity reaches 90
GOMEL09 July 15-26 FZiaziula 17
However with light recording of the short duration (less than 1 μs) it is necessary to use the external wideband amplifier whose noise does not make it possible to register the flash of light with the number of photons of less than 1000 Furthermore relatively great thickness of the depletion layer makes p-i-n photodiodes sensitive to others emissions (gamma-quanta the charged particles)

(256x256 possible) active readout and contro lwith threshold management
GOMEL09 July 15-26 FZiaziula 18
In the detectors of the second group the internal amplification of charge occurs as a rule due to the impact ionization of carriers in the high electric fields Under the action of field free charge carrier (electron or hole) obtain energy sufficient for the ionization of neutral atom and release one additional electron hole pair this process can be repeated repeatedly Semiconductor detectors with the internal strengthening of charge caused by impact ionization avalanche photodiodes (APD) ) were developed more than 50 years agoMerits of APD - high speed operation and quantum effectiveness (to 90) and also broad dynamic band Mu-factor of the industrial standards of silica APD which work in the proportional regime (ie with the signal at the output APD proportional to the intensity of recorded light) comprises ~102
Thus to record single photons by the traditional detectors on the basis of p-n junction which workin the proportional regime of amplification is impossible
GOMEL09 July 15-26 FZiaziula 19
Special technologies make it possible to make APD with the mu-factor to ~103 With this mu-factor the signal from the single photoelectron can exceed the level of noise of amplifier however the fluctuations of multiplication factor in APD do not make it possible to register the light pulses which contain less than 20-50 photonsTo increase the multiplication factor of traditional silica APD to 104 or more is impossible for the thermal breakdown of p-n- junction and the failure of instrumentHowever the way has been found allowing to increase amplification It is a creation of structure in which the avalanche discharge is limited to a feedback mechanism Works in this direction to Russia were spent at Physical institute of PNLebedev of the Russian Academy of Sciences where the structure of type metal-dielectric-semiconductor (MDS)] was investigated In such structures carriers appearing during an avalanche collect on border has undressed the semiconductor-dielectric that leads to local decrease in intensity of electric field reduction of factors of shock ionization and the termination of formation of an avalanche mode
GOMEL09 July 15-26 FZiaziula 20
The basic lacks of MDP-structures - necessity of giving the pulse voltage power supply and degradation of characteristics of the device
Problems have been solved at use of structures metal-resistive a layer-semiconductor (MRS) It has allowed to increase essentially factor of strengthening of a photocurrent (to 104) to improve stability of characteristics to increase the area of a sensitive surface and service life of devices
bullSimultaneously in a number of world laboratories possibility of application for registration of single photons of the p-n-junction working in an avalanche mode at voltage above breakdown was studied ie in a Geiger mode Geiger Such detectors named SPAD (Single Photon Avalanche Diode) are capable to register single photons with efficiency to 80 In Geiger mode the signal from one photon arriving on 50 Ohm loading can make some volt
GOMEL09 July 15-26 FZiaziula 21
Lack SPAD - the fixed amplitude output signal and also tolerance of the detector to
external influence during the period after operation and till the restoration moment
The next step achieved with the novel photo-detectors developed in Russia Silicon
Photomultipliers (SiPMs) at the beginning of this millennium
Pulse height spectrum of weaklight flashes measured with a G-APD
This device can detect single photons like a PMT and therefore some people call it Silicon PhotoMultiplier SiPM The pulse height spectrum measured with a G-APD shows a resolution which is even better than what can be achieved with a photomultiplier and even with a hybrid photomultiplier tube
GOMEL09 July 15-26 FZiaziula 22
SiPM what is itThe MRS (Metal-Resistor-Silicon) structure SiPM (Silicon PhotoMultiplier) is a new type of Geiger-mode avalanche photodiode that shows promise for use with scintillators They have recently been tested as possible detectors for the hadron calorimeter tiles for the next-generation International Linear Collider The SiPM is a p-n junction diode that is biased above the breakdown voltage in order to create a Geiger avalanche Structure of the micropixel of a SiPM
The resulting depletion region in this device is of the order of just 5microm
with an avalanche region of around 1microm Such a thickness is sufficient for
optical photon detection The Geiger avalanche is passively quenched by
a resistive load in series with the diode In the MRS structure of this
SiPM the resistive load takes the form of a special technology layer
deposited on the diode surface
GOMEL09 July 15-26 FZiaziula 23
SiPM what is
it
By using the high-resistivity material SiC the resistor element can be made small
whilst providing adequate quenching
A semi-transparent metal contact layer on top of the quenching resistance forms the electrode
GOMEL09 July 15-26 FZiaziula 24
SiPMT is a photodetector on the basis of the ordered set (matrix) of the p-n-junction (cells) executed on the general substrate The characteristic size of a cell is an order 30-100 microns Density of packing of a matrix - about 100-1000 cellsmm2 The area of the sensitive surface SiPMT may lays in limits from 1times1 to 5times5 mm2 and more All cells are identical All of them are united in the general point by current-carrying bus Displacement voltage of all cells the general It on some volts (value of an overvoltage) exceeds voltage of breakdown of p-n junction Each cell contains current-limiting resistor Therefore Geiger breakdown current in a cell is limited The signal of each cell - logic also does not depend on number of the initial carriers which have caused operation of a cell
SiPMT itself as whole represents the analogue detector as its output signal is equal to the sum ofidentical signals of the p-n junctions which have operated at absorption by them of photons

The energy resolution of CMS ECAL meets the design goal for the detector For uniform illumination of a crystal with 120 GeV electrons a resolution of 05 was achieved
The avalanche photodiode (APD) developed for the electromagnetic calorimeter of CMS has a thin p-doped layer of silicon in front of the p-n junction where the photo conversion takes place The created electrons are amplified The internal gain of an APD improves the signal to noise ratio but the excess noise factor (avalanche fluctuations) and the gain sensitivity to voltage and temperature variations contribute to the energy resolution

The business concerns already letting out first samples of such detectors (Photonique SensL RMD) or planning their release (Photonis Siemens) Company Hamamatsu Photonics developing SiPMT under name MPPC (Multy-Pixel Photon Counter) has achieved the big successes Already today it is possible to find in the Internet proposal about sale of the detectors similar SiPMT Their price is still rather high however it is possible to expect that in the future it will not exceed several dollars on 1 square мм

SOLID STATE DETECTORSThe main disadvantages which impede use PMT in some specific applications are large sizes the high voltage of power supply and sensitivity to the magnetic fields Furthermore during the construction of the systems which contain hundred thousand channels of registration important factor becomes the price of detector which in the case PMT is sufficiently highThese factors became the reason for the active development of the solid-state instruments which use a phenomenon of the photoconductive effect The semiconductor detectors of photons can be divided into two large groups the photodetectors in which the transformation of light signal occurs bullwithout the internal amplification of chargebull photodetectors with the internal amplification of charge The first group includes the p-i-n photodiodes which because of their reliability compactness and low cost successfully adapt in different physical experimentsThe quantum effectiveness of these photodiodes in the maximum of spectral sensitivity reaches 90

However with light recording of the short duration (less than 1 μs) it is necessary to use the external wideband amplifier whose noise does not make it possible to register the flash of light with the number of photons of less than 1000 Furthermore relatively great thickness of the depletion layer makes p-i-n photodiodes sensitive to others emissions (gamma-quanta the charged particles)

In the detectors of the second group the internal amplification of charge occurs as a rule due to the impact ionization of carriers in the high electric fields Under the action of field free charge carrier (electron or hole) obtain energy sufficient for the ionization of neutral atom and release one additional electron hole pair this process can be repeated repeatedly Semiconductor detectors with the internal strengthening of charge caused by impact ionization avalanche photodiodes (APD) ) were developed more than 50 years agoMerits of APD - high speed operation and quantum effectiveness (to 90) and also broad dynamic band Mu-factor of the industrial standards of silica APD which work in the proportional regime (ie with the signal at the output APD proportional to the intensity of recorded light) comprises ~102

The resulting depletion region in this device is of the order of just 5microm

SOLID STATE DETECTORSThe main disadvantages which impede use PMT in some specific applications are large sizes the high voltage of power supply and sensitivity to the magnetic fields Furthermore during the construction of the systems which contain hundred thousand channels of registration important factor becomes the price of detector which in the case PMT is sufficiently highThese factors became the reason for the active development of the solid-state instruments which use a phenomenon of the photoconductive effect The semiconductor detectors of photons can be divided into two large groups the photodetectors in which the transformation of light signal occurs bullwithout the internal amplification of chargebull photodetectors with the internal amplification of charge The first group includes the p-i-n photodiodes which because of their reliability compactness and low cost successfully adapt in different physical experimentsThe quantum effectiveness of these photodiodes in the maximum of spectral sensitivity reaches 90
GOMEL09 July 15-26 FZiaziula 17
However with light recording of the short duration (less than 1 μs) it is necessary to use the external wideband amplifier whose noise does not make it possible to register the flash of light with the number of photons of less than 1000 Furthermore relatively great thickness of the depletion layer makes p-i-n photodiodes sensitive to others emissions (gamma-quanta the charged particles)

In the detectors of the second group the internal amplification of charge occurs as a rule due to the impact ionization of carriers in the high electric fields Under the action of field free charge carrier (electron or hole) obtain energy sufficient for the ionization of neutral atom and release one additional electron hole pair this process can be repeated repeatedly Semiconductor detectors with the internal strengthening of charge caused by impact ionization avalanche photodiodes (APD) ) were developed more than 50 years agoMerits of APD - high speed operation and quantum effectiveness (to 90) and also broad dynamic band Mu-factor of the industrial standards of silica APD which work in the proportional regime (ie with the signal at the output APD proportional to the intensity of recorded light) comprises ~102
Thus to record single photons by the traditional detectors on the basis of p-n junction which workin the proportional regime of amplification is impossible
GOMEL09 July 15-26 FZiaziula 19
Special technologies make it possible to make APD with the mu-factor to ~103 With this mu-factor the signal from the single photoelectron can exceed the level of noise of amplifier however the fluctuations of multiplication factor in APD do not make it possible to register the light pulses which contain less than 20-50 photonsTo increase the multiplication factor of traditional silica APD to 104 or more is impossible for the thermal breakdown of p-n- junction and the failure of instrumentHowever the way has been found allowing to increase amplification It is a creation of structure in which the avalanche discharge is limited to a feedback mechanism Works in this direction to Russia were spent at Physical institute of PNLebedev of the Russian Academy of Sciences where the structure of type metal-dielectric-semiconductor (MDS)] was investigated In such structures carriers appearing during an avalanche collect on border has undressed the semiconductor-dielectric that leads to local decrease in intensity of electric field reduction of factors of shock ionization and the termination of formation of an avalanche mode

The basic lacks of MDP-structures - necessity of giving the pulse voltage power supply and degradation of characteristics of the device
Problems have been solved at use of structures metal-resistive a layer-semiconductor (MRS) It has allowed to increase essentially factor of strengthening of a photocurrent (to 104) to improve stability of characteristics to increase the area of a sensitive surface and service life of devices
bullSimultaneously in a number of world laboratories possibility of application for registration of single photons of the p-n-junction working in an avalanche mode at voltage above breakdown was studied ie in a Geiger mode Geiger Such detectors named SPAD (Single Photon Avalanche Diode) are capable to register single photons with efficiency to 80 In Geiger mode the signal from one photon arriving on 50 Ohm loading can make some volt

SOLID STATE DETECTORSThe main disadvantages which impede use PMT in some specific applications are large sizes the high voltage of power supply and sensitivity to the magnetic fields Furthermore during the construction of the systems which contain hundred thousand channels of registration important factor becomes the price of detector which in the case PMT is sufficiently highThese factors became the reason for the active development of the solid-state instruments which use a phenomenon of the photoconductive effect The semiconductor detectors of photons can be divided into two large groups the photodetectors in which the transformation of light signal occurs bullwithout the internal amplification of chargebull photodetectors with the internal amplification of charge The first group includes the p-i-n photodiodes which because of their reliability compactness and low cost successfully adapt in different physical experimentsThe quantum effectiveness of these photodiodes in the maximum of spectral sensitivity reaches 90
GOMEL09 July 15-26 FZiaziula 17
However with light recording of the short duration (less than 1 μs) it is necessary to use the external wideband amplifier whose noise does not make it possible to register the flash of light with the number of photons of less than 1000 Furthermore relatively great thickness of the depletion layer makes p-i-n photodiodes sensitive to others emissions (gamma-quanta the charged particles)

GOMEL09 July 15-26 FZiaziula 18
In the detectors of the second group the internal amplification of charge occurs as a rule due to the impact ionization of carriers in the high electric fields Under the action of field free charge carrier (electron or hole) obtain energy sufficient for the ionization of neutral atom and release one additional electron hole pair this process can be repeated repeatedly Semiconductor detectors with the internal strengthening of charge caused by impact ionization avalanche photodiodes (APD) ) were developed more than 50 years agoMerits of APD - high speed operation and quantum effectiveness (to 90) and also broad dynamic band Mu-factor of the industrial standards of silica APD which work in the proportional regime (ie with the signal at the output APD proportional to the intensity of recorded light) comprises ~102
Thus to record single photons by the traditional detectors on the basis of p-n junction which workin the proportional regime of amplification is impossible
GOMEL09 July 15-26 FZiaziula 19
Special technologies make it possible to make APD with the mu-factor to ~103 With this mu-factor the signal from the single photoelectron can exceed the level of noise of amplifier however the fluctuations of multiplication factor in APD do not make it possible to register the light pulses which contain less than 20-50 photonsTo increase the multiplication factor of traditional silica APD to 104 or more is impossible for the thermal breakdown of p-n- junction and the failure of instrumentHowever the way has been found allowing to increase amplification It is a creation of structure in which the avalanche discharge is limited to a feedback mechanism Works in this direction to Russia were spent at Physical institute of PNLebedev of the Russian Academy of Sciences where the structure of type metal-dielectric-semiconductor (MDS)] was investigated In such structures carriers appearing during an avalanche collect on border has undressed the semiconductor-dielectric that leads to local decrease in intensity of electric field reduction of factors of shock ionization and the termination of formation of an avalanche mode

The basic lacks of MDP-structures - necessity of giving the pulse voltage power supply and degradation of characteristics of the device
Problems have been solved at use of structures metal-resistive a layer-semiconductor (MRS) It has allowed to increase essentially factor of strengthening of a photocurrent (to 104) to improve stability of characteristics to increase the area of a sensitive surface and service life of devices
bullSimultaneously in a number of world laboratories possibility of application for registration of single photons of the p-n-junction working in an avalanche mode at voltage above breakdown was studied ie in a Geiger mode Geiger Such detectors named SPAD (Single Photon Avalanche Diode) are capable to register single photons with efficiency to 80 In Geiger mode the signal from one photon arriving on 50 Ohm loading can make some volt

SiPM what is itThe MRS (Metal-Resistor-Silicon) structure SiPM (Silicon PhotoMultiplier) is a new type of Geiger-mode avalanche photodiode that shows promise for use with scintillators They have recently been tested as possible detectors for the hadron calorimeter tiles for the next-generation International Linear Collider The SiPM is a p-n junction diode that is biased above the breakdown voltage in order to create a Geiger avalanche Structure of the micropixel of a SiPM
The resulting depletion region in this device is of the order of just 5microm
with an avalanche region of around 1microm Such a thickness is sufficient for
optical photon detection The Geiger avalanche is passively quenched by
a resistive load in series with the diode In the MRS structure of this
SiPM the resistive load takes the form of a special technology layer
deposited on the diode surface

SiPMT is a photodetector on the basis of the ordered set (matrix) of the p-n-junction (cells) executed on the general substrate The characteristic size of a cell is an order 30-100 microns Density of packing of a matrix - about 100-1000 cellsmm2 The area of the sensitive surface SiPMT may lays in limits from 1times1 to 5times5 mm2 and more All cells are identical All of them are united in the general point by current-carrying bus Displacement voltage of all cells the general It on some volts (value of an overvoltage) exceeds voltage of breakdown of p-n junction Each cell contains current-limiting resistor Therefore Geiger breakdown current in a cell is limited The signal of each cell - logic also does not depend on number of the initial carriers which have caused operation of a cell

SOLID STATE DETECTORSThe main disadvantages which impede use PMT in some specific applications are large sizes the high voltage of power supply and sensitivity to the magnetic fields Furthermore during the construction of the systems which contain hundred thousand channels of registration important factor becomes the price of detector which in the case PMT is sufficiently highThese factors became the reason for the active development of the solid-state instruments which use a phenomenon of the photoconductive effect The semiconductor detectors of photons can be divided into two large groups the photodetectors in which the transformation of light signal occurs bullwithout the internal amplification of chargebull photodetectors with the internal amplification of charge The first group includes the p-i-n photodiodes which because of their reliability compactness and low cost successfully adapt in different physical experimentsThe quantum effectiveness of these photodiodes in the maximum of spectral sensitivity reaches 90
GOMEL09 July 15-26 FZiaziula 17
However with light recording of the short duration (less than 1 μs) it is necessary to use the external wideband amplifier whose noise does not make it possible to register the flash of light with the number of photons of less than 1000 Furthermore relatively great thickness of the depletion layer makes p-i-n photodiodes sensitive to others emissions (gamma-quanta the charged particles)

(256x256 possible) active readout and contro lwith threshold management
GOMEL09 July 15-26 FZiaziula 18
In the detectors of the second group the internal amplification of charge occurs as a rule due to the impact ionization of carriers in the high electric fields Under the action of field free charge carrier (electron or hole) obtain energy sufficient for the ionization of neutral atom and release one additional electron hole pair this process can be repeated repeatedly Semiconductor detectors with the internal strengthening of charge caused by impact ionization avalanche photodiodes (APD) ) were developed more than 50 years agoMerits of APD - high speed operation and quantum effectiveness (to 90) and also broad dynamic band Mu-factor of the industrial standards of silica APD which work in the proportional regime (ie with the signal at the output APD proportional to the intensity of recorded light) comprises ~102
Thus to record single photons by the traditional detectors on the basis of p-n junction which workin the proportional regime of amplification is impossible
GOMEL09 July 15-26 FZiaziula 19
Special technologies make it possible to make APD with the mu-factor to ~103 With this mu-factor the signal from the single photoelectron can exceed the level of noise of amplifier however the fluctuations of multiplication factor in APD do not make it possible to register the light pulses which contain less than 20-50 photonsTo increase the multiplication factor of traditional silica APD to 104 or more is impossible for the thermal breakdown of p-n- junction and the failure of instrumentHowever the way has been found allowing to increase amplification It is a creation of structure in which the avalanche discharge is limited to a feedback mechanism Works in this direction to Russia were spent at Physical institute of PNLebedev of the Russian Academy of Sciences where the structure of type metal-dielectric-semiconductor (MDS)] was investigated In such structures carriers appearing during an avalanche collect on border has undressed the semiconductor-dielectric that leads to local decrease in intensity of electric field reduction of factors of shock ionization and the termination of formation of an avalanche mode
GOMEL09 July 15-26 FZiaziula 20
The basic lacks of MDP-structures - necessity of giving the pulse voltage power supply and degradation of characteristics of the device
Problems have been solved at use of structures metal-resistive a layer-semiconductor (MRS) It has allowed to increase essentially factor of strengthening of a photocurrent (to 104) to improve stability of characteristics to increase the area of a sensitive surface and service life of devices
bullSimultaneously in a number of world laboratories possibility of application for registration of single photons of the p-n-junction working in an avalanche mode at voltage above breakdown was studied ie in a Geiger mode Geiger Such detectors named SPAD (Single Photon Avalanche Diode) are capable to register single photons with efficiency to 80 In Geiger mode the signal from one photon arriving on 50 Ohm loading can make some volt
GOMEL09 July 15-26 FZiaziula 21
Lack SPAD - the fixed amplitude output signal and also tolerance of the detector to
external influence during the period after operation and till the restoration moment
The next step achieved with the novel photo-detectors developed in Russia Silicon
Photomultipliers (SiPMs) at the beginning of this millennium
Pulse height spectrum of weaklight flashes measured with a G-APD
This device can detect single photons like a PMT and therefore some people call it Silicon PhotoMultiplier SiPM The pulse height spectrum measured with a G-APD shows a resolution which is even better than what can be achieved with a photomultiplier and even with a hybrid photomultiplier tube
GOMEL09 July 15-26 FZiaziula 22
SiPM what is itThe MRS (Metal-Resistor-Silicon) structure SiPM (Silicon PhotoMultiplier) is a new type of Geiger-mode avalanche photodiode that shows promise for use with scintillators They have recently been tested as possible detectors for the hadron calorimeter tiles for the next-generation International Linear Collider The SiPM is a p-n junction diode that is biased above the breakdown voltage in order to create a Geiger avalanche Structure of the micropixel of a SiPM
The resulting depletion region in this device is of the order of just 5microm
with an avalanche region of around 1microm Such a thickness is sufficient for
optical photon detection The Geiger avalanche is passively quenched by
a resistive load in series with the diode In the MRS structure of this
SiPM the resistive load takes the form of a special technology layer
deposited on the diode surface
GOMEL09 July 15-26 FZiaziula 23
SiPM what is
it
By using the high-resistivity material SiC the resistor element can be made small
whilst providing adequate quenching
A semi-transparent metal contact layer on top of the quenching resistance forms the electrode
GOMEL09 July 15-26 FZiaziula 24
SiPMT is a photodetector on the basis of the ordered set (matrix) of the p-n-junction (cells) executed on the general substrate The characteristic size of a cell is an order 30-100 microns Density of packing of a matrix - about 100-1000 cellsmm2 The area of the sensitive surface SiPMT may lays in limits from 1times1 to 5times5 mm2 and more All cells are identical All of them are united in the general point by current-carrying bus Displacement voltage of all cells the general It on some volts (value of an overvoltage) exceeds voltage of breakdown of p-n junction Each cell contains current-limiting resistor Therefore Geiger breakdown current in a cell is limited The signal of each cell - logic also does not depend on number of the initial carriers which have caused operation of a cell
SiPMT itself as whole represents the analogue detector as its output signal is equal to the sum ofidentical signals of the p-n junctions which have operated at absorption by them of photons

The energy resolution of CMS ECAL meets the design goal for the detector For uniform illumination of a crystal with 120 GeV electrons a resolution of 05 was achieved
The avalanche photodiode (APD) developed for the electromagnetic calorimeter of CMS has a thin p-doped layer of silicon in front of the p-n junction where the photo conversion takes place The created electrons are amplified The internal gain of an APD improves the signal to noise ratio but the excess noise factor (avalanche fluctuations) and the gain sensitivity to voltage and temperature variations contribute to the energy resolution

SOLID STATE DETECTORSThe main disadvantages which impede use PMT in some specific applications are large sizes the high voltage of power supply and sensitivity to the magnetic fields Furthermore during the construction of the systems which contain hundred thousand channels of registration important factor becomes the price of detector which in the case PMT is sufficiently highThese factors became the reason for the active development of the solid-state instruments which use a phenomenon of the photoconductive effect The semiconductor detectors of photons can be divided into two large groups the photodetectors in which the transformation of light signal occurs bullwithout the internal amplification of chargebull photodetectors with the internal amplification of charge The first group includes the p-i-n photodiodes which because of their reliability compactness and low cost successfully adapt in different physical experimentsThe quantum effectiveness of these photodiodes in the maximum of spectral sensitivity reaches 90
GOMEL09 July 15-26 FZiaziula 17
However with light recording of the short duration (less than 1 μs) it is necessary to use the external wideband amplifier whose noise does not make it possible to register the flash of light with the number of photons of less than 1000 Furthermore relatively great thickness of the depletion layer makes p-i-n photodiodes sensitive to others emissions (gamma-quanta the charged particles)

In the detectors of the second group the internal amplification of charge occurs as a rule due to the impact ionization of carriers in the high electric fields Under the action of field free charge carrier (electron or hole) obtain energy sufficient for the ionization of neutral atom and release one additional electron hole pair this process can be repeated repeatedly Semiconductor detectors with the internal strengthening of charge caused by impact ionization avalanche photodiodes (APD) ) were developed more than 50 years agoMerits of APD - high speed operation and quantum effectiveness (to 90) and also broad dynamic band Mu-factor of the industrial standards of silica APD which work in the proportional regime (ie with the signal at the output APD proportional to the intensity of recorded light) comprises ~102
Thus to record single photons by the traditional detectors on the basis of p-n junction which workin the proportional regime of amplification is impossible
GOMEL09 July 15-26 FZiaziula 19
Special technologies make it possible to make APD with the mu-factor to ~103 With this mu-factor the signal from the single photoelectron can exceed the level of noise of amplifier however the fluctuations of multiplication factor in APD do not make it possible to register the light pulses which contain less than 20-50 photonsTo increase the multiplication factor of traditional silica APD to 104 or more is impossible for the thermal breakdown of p-n- junction and the failure of instrumentHowever the way has been found allowing to increase amplification It is a creation of structure in which the avalanche discharge is limited to a feedback mechanism Works in this direction to Russia were spent at Physical institute of PNLebedev of the Russian Academy of Sciences where the structure of type metal-dielectric-semiconductor (MDS)] was investigated In such structures carriers appearing during an avalanche collect on border has undressed the semiconductor-dielectric that leads to local decrease in intensity of electric field reduction of factors of shock ionization and the termination of formation of an avalanche mode

The basic lacks of MDP-structures - necessity of giving the pulse voltage power supply and degradation of characteristics of the device
Problems have been solved at use of structures metal-resistive a layer-semiconductor (MRS) It has allowed to increase essentially factor of strengthening of a photocurrent (to 104) to improve stability of characteristics to increase the area of a sensitive surface and service life of devices
bullSimultaneously in a number of world laboratories possibility of application for registration of single photons of the p-n-junction working in an avalanche mode at voltage above breakdown was studied ie in a Geiger mode Geiger Such detectors named SPAD (Single Photon Avalanche Diode) are capable to register single photons with efficiency to 80 In Geiger mode the signal from one photon arriving on 50 Ohm loading can make some volt

Pulse height spectrum of weaklight flashes measured with a G-APD
This device can detect single photons like a PMT and therefore some people call it Silicon PhotoMultiplier SiPM The pulse height spectrum measured with a G-APD shows a resolution which is even better than what can be achieved with a photomultiplier and even with a hybrid photomultiplier tube

SiPM what is itThe MRS (Metal-Resistor-Silicon) structure SiPM (Silicon PhotoMultiplier) is a new type of Geiger-mode avalanche photodiode that shows promise for use with scintillators They have recently been tested as possible detectors for the hadron calorimeter tiles for the next-generation International Linear Collider The SiPM is a p-n junction diode that is biased above the breakdown voltage in order to create a Geiger avalanche Structure of the micropixel of a SiPM
The resulting depletion region in this device is of the order of just 5microm
with an avalanche region of around 1microm Such a thickness is sufficient for
optical photon detection The Geiger avalanche is passively quenched by
a resistive load in series with the diode In the MRS structure of this
SiPM the resistive load takes the form of a special technology layer
deposited on the diode surface

SiPMT is a photodetector on the basis of the ordered set (matrix) of the p-n-junction (cells) executed on the general substrate The characteristic size of a cell is an order 30-100 microns Density of packing of a matrix - about 100-1000 cellsmm2 The area of the sensitive surface SiPMT may lays in limits from 1times1 to 5times5 mm2 and more All cells are identical All of them are united in the general point by current-carrying bus Displacement voltage of all cells the general It on some volts (value of an overvoltage) exceeds voltage of breakdown of p-n junction Each cell contains current-limiting resistor Therefore Geiger breakdown current in a cell is limited The signal of each cell - logic also does not depend on number of the initial carriers which have caused operation of a cell

SOLID STATE DETECTORSThe main disadvantages which impede use PMT in some specific applications are large sizes the high voltage of power supply and sensitivity to the magnetic fields Furthermore during the construction of the systems which contain hundred thousand channels of registration important factor becomes the price of detector which in the case PMT is sufficiently highThese factors became the reason for the active development of the solid-state instruments which use a phenomenon of the photoconductive effect The semiconductor detectors of photons can be divided into two large groups the photodetectors in which the transformation of light signal occurs bullwithout the internal amplification of chargebull photodetectors with the internal amplification of charge The first group includes the p-i-n photodiodes which because of their reliability compactness and low cost successfully adapt in different physical experimentsThe quantum effectiveness of these photodiodes in the maximum of spectral sensitivity reaches 90
GOMEL09 July 15-26 FZiaziula 17
However with light recording of the short duration (less than 1 μs) it is necessary to use the external wideband amplifier whose noise does not make it possible to register the flash of light with the number of photons of less than 1000 Furthermore relatively great thickness of the depletion layer makes p-i-n photodiodes sensitive to others emissions (gamma-quanta the charged particles)

GOMEL09 July 15-26 FZiaziula 18
In the detectors of the second group the internal amplification of charge occurs as a rule due to the impact ionization of carriers in the high electric fields Under the action of field free charge carrier (electron or hole) obtain energy sufficient for the ionization of neutral atom and release one additional electron hole pair this process can be repeated repeatedly Semiconductor detectors with the internal strengthening of charge caused by impact ionization avalanche photodiodes (APD) ) were developed more than 50 years agoMerits of APD - high speed operation and quantum effectiveness (to 90) and also broad dynamic band Mu-factor of the industrial standards of silica APD which work in the proportional regime (ie with the signal at the output APD proportional to the intensity of recorded light) comprises ~102
Thus to record single photons by the traditional detectors on the basis of p-n junction which workin the proportional regime of amplification is impossible
GOMEL09 July 15-26 FZiaziula 19
Special technologies make it possible to make APD with the mu-factor to ~103 With this mu-factor the signal from the single photoelectron can exceed the level of noise of amplifier however the fluctuations of multiplication factor in APD do not make it possible to register the light pulses which contain less than 20-50 photonsTo increase the multiplication factor of traditional silica APD to 104 or more is impossible for the thermal breakdown of p-n- junction and the failure of instrumentHowever the way has been found allowing to increase amplification It is a creation of structure in which the avalanche discharge is limited to a feedback mechanism Works in this direction to Russia were spent at Physical institute of PNLebedev of the Russian Academy of Sciences where the structure of type metal-dielectric-semiconductor (MDS)] was investigated In such structures carriers appearing during an avalanche collect on border has undressed the semiconductor-dielectric that leads to local decrease in intensity of electric field reduction of factors of shock ionization and the termination of formation of an avalanche mode

The basic lacks of MDP-structures - necessity of giving the pulse voltage power supply and degradation of characteristics of the device
Problems have been solved at use of structures metal-resistive a layer-semiconductor (MRS) It has allowed to increase essentially factor of strengthening of a photocurrent (to 104) to improve stability of characteristics to increase the area of a sensitive surface and service life of devices
bullSimultaneously in a number of world laboratories possibility of application for registration of single photons of the p-n-junction working in an avalanche mode at voltage above breakdown was studied ie in a Geiger mode Geiger Such detectors named SPAD (Single Photon Avalanche Diode) are capable to register single photons with efficiency to 80 In Geiger mode the signal from one photon arriving on 50 Ohm loading can make some volt
GOMEL09 July 15-26 FZiaziula 21
Lack SPAD - the fixed amplitude output signal and also tolerance of the detector to
external influence during the period after operation and till the restoration moment
The next step achieved with the novel photo-detectors developed in Russia Silicon
Photomultipliers (SiPMs) at the beginning of this millennium
Pulse height spectrum of weaklight flashes measured with a G-APD
This device can detect single photons like a PMT and therefore some people call it Silicon PhotoMultiplier SiPM The pulse height spectrum measured with a G-APD shows a resolution which is even better than what can be achieved with a photomultiplier and even with a hybrid photomultiplier tube
GOMEL09 July 15-26 FZiaziula 22
SiPM what is itThe MRS (Metal-Resistor-Silicon) structure SiPM (Silicon PhotoMultiplier) is a new type of Geiger-mode avalanche photodiode that shows promise for use with scintillators They have recently been tested as possible detectors for the hadron calorimeter tiles for the next-generation International Linear Collider The SiPM is a p-n junction diode that is biased above the breakdown voltage in order to create a Geiger avalanche Structure of the micropixel of a SiPM
The resulting depletion region in this device is of the order of just 5microm
with an avalanche region of around 1microm Such a thickness is sufficient for
optical photon detection The Geiger avalanche is passively quenched by
a resistive load in series with the diode In the MRS structure of this
SiPM the resistive load takes the form of a special technology layer
deposited on the diode surface

SiPMT is a photodetector on the basis of the ordered set (matrix) of the p-n-junction (cells) executed on the general substrate The characteristic size of a cell is an order 30-100 microns Density of packing of a matrix - about 100-1000 cellsmm2 The area of the sensitive surface SiPMT may lays in limits from 1times1 to 5times5 mm2 and more All cells are identical All of them are united in the general point by current-carrying bus Displacement voltage of all cells the general It on some volts (value of an overvoltage) exceeds voltage of breakdown of p-n junction Each cell contains current-limiting resistor Therefore Geiger breakdown current in a cell is limited The signal of each cell - logic also does not depend on number of the initial carriers which have caused operation of a cell
SiPMT itself as whole represents the analogue detector as its output signal is equal to the sum ofidentical signals of the p-n junctions which have operated at absorption by them of photons

SOLID STATE DETECTORSThe main disadvantages which impede use PMT in some specific applications are large sizes the high voltage of power supply and sensitivity to the magnetic fields Furthermore during the construction of the systems which contain hundred thousand channels of registration important factor becomes the price of detector which in the case PMT is sufficiently highThese factors became the reason for the active development of the solid-state instruments which use a phenomenon of the photoconductive effect The semiconductor detectors of photons can be divided into two large groups the photodetectors in which the transformation of light signal occurs bullwithout the internal amplification of chargebull photodetectors with the internal amplification of charge The first group includes the p-i-n photodiodes which because of their reliability compactness and low cost successfully adapt in different physical experimentsThe quantum effectiveness of these photodiodes in the maximum of spectral sensitivity reaches 90

However with light recording of the short duration (less than 1 μs) it is necessary to use the external wideband amplifier whose noise does not make it possible to register the flash of light with the number of photons of less than 1000 Furthermore relatively great thickness of the depletion layer makes p-i-n photodiodes sensitive to others emissions (gamma-quanta the charged particles)

In the detectors of the second group the internal amplification of charge occurs as a rule due to the impact ionization of carriers in the high electric fields Under the action of field free charge carrier (electron or hole) obtain energy sufficient for the ionization of neutral atom and release one additional electron hole pair this process can be repeated repeatedly Semiconductor detectors with the internal strengthening of charge caused by impact ionization avalanche photodiodes (APD) ) were developed more than 50 years agoMerits of APD - high speed operation and quantum effectiveness (to 90) and also broad dynamic band Mu-factor of the industrial standards of silica APD which work in the proportional regime (ie with the signal at the output APD proportional to the intensity of recorded light) comprises ~102
Thus to record single photons by the traditional detectors on the basis of p-n junction which workin the proportional regime of amplification is impossible
GOMEL09 July 15-26 FZiaziula 19
Special technologies make it possible to make APD with the mu-factor to ~103 With this mu-factor the signal from the single photoelectron can exceed the level of noise of amplifier however the fluctuations of multiplication factor in APD do not make it possible to register the light pulses which contain less than 20-50 photonsTo increase the multiplication factor of traditional silica APD to 104 or more is impossible for the thermal breakdown of p-n- junction and the failure of instrumentHowever the way has been found allowing to increase amplification It is a creation of structure in which the avalanche discharge is limited to a feedback mechanism Works in this direction to Russia were spent at Physical institute of PNLebedev of the Russian Academy of Sciences where the structure of type metal-dielectric-semiconductor (MDS)] was investigated In such structures carriers appearing during an avalanche collect on border has undressed the semiconductor-dielectric that leads to local decrease in intensity of electric field reduction of factors of shock ionization and the termination of formation of an avalanche mode

The basic lacks of MDP-structures - necessity of giving the pulse voltage power supply and degradation of characteristics of the device
Problems have been solved at use of structures metal-resistive a layer-semiconductor (MRS) It has allowed to increase essentially factor of strengthening of a photocurrent (to 104) to improve stability of characteristics to increase the area of a sensitive surface and service life of devices
bullSimultaneously in a number of world laboratories possibility of application for registration of single photons of the p-n-junction working in an avalanche mode at voltage above breakdown was studied ie in a Geiger mode Geiger Such detectors named SPAD (Single Photon Avalanche Diode) are capable to register single photons with efficiency to 80 In Geiger mode the signal from one photon arriving on 50 Ohm loading can make some volt

SiPM what is itThe MRS (Metal-Resistor-Silicon) structure SiPM (Silicon PhotoMultiplier) is a new type of Geiger-mode avalanche photodiode that shows promise for use with scintillators They have recently been tested as possible detectors for the hadron calorimeter tiles for the next-generation International Linear Collider The SiPM is a p-n junction diode that is biased above the breakdown voltage in order to create a Geiger avalanche Structure of the micropixel of a SiPM
The resulting depletion region in this device is of the order of just 5microm
with an avalanche region of around 1microm Such a thickness is sufficient for
optical photon detection The Geiger avalanche is passively quenched by

The crystal ball for the measurement of pibeta decay π+rarrπ0+e++ν followed by π0rarrγ+γ which has a branching ratio of 10-8 is made of 240 pure CsI crystals The crystal readout needs to cover the large area of the rear crystal face it has
to be very sensitive because the light yield of pure CsI is only few percent compared to NaI(Tl) and it has to be fast in order to allow an efficient
suppression of accidental coincidences The choice was a fast 10-stage PMT with 78 mm diameter from Electron Tubes The PMTrsquos have a quartz entrance window (emission wavelength of pure CsI is 315 nm) and are directly glued to

SOLID STATE DETECTORSThe main disadvantages which impede use PMT in some specific applications are large sizes the high voltage of power supply and sensitivity to the magnetic fields Furthermore during the construction of the systems which contain hundred thousand channels of registration important factor becomes the price of detector which in the case PMT is sufficiently highThese factors became the reason for the active development of the solid-state instruments which use a phenomenon of the photoconductive effect The semiconductor detectors of photons can be divided into two large groups the photodetectors in which the transformation of light signal occurs bullwithout the internal amplification of chargebull photodetectors with the internal amplification of charge The first group includes the p-i-n photodiodes which because of their reliability compactness and low cost successfully adapt in different physical experimentsThe quantum effectiveness of these photodiodes in the maximum of spectral sensitivity reaches 90
GOMEL09 July 15-26 FZiaziula 17
However with light recording of the short duration (less than 1 μs) it is necessary to use the external wideband amplifier whose noise does not make it possible to register the flash of light with the number of photons of less than 1000 Furthermore relatively great thickness of the depletion layer makes p-i-n photodiodes sensitive to others emissions (gamma-quanta the charged particles)

GOMEL09 July 15-26 FZiaziula 18
In the detectors of the second group the internal amplification of charge occurs as a rule due to the impact ionization of carriers in the high electric fields Under the action of field free charge carrier (electron or hole) obtain energy sufficient for the ionization of neutral atom and release one additional electron hole pair this process can be repeated repeatedly Semiconductor detectors with the internal strengthening of charge caused by impact ionization avalanche photodiodes (APD) ) were developed more than 50 years agoMerits of APD - high speed operation and quantum effectiveness (to 90) and also broad dynamic band Mu-factor of the industrial standards of silica APD which work in the proportional regime (ie with the signal at the output APD proportional to the intensity of recorded light) comprises ~102
Thus to record single photons by the traditional detectors on the basis of p-n junction which workin the proportional regime of amplification is impossible
GOMEL09 July 15-26 FZiaziula 19
Special technologies make it possible to make APD with the mu-factor to ~103 With this mu-factor the signal from the single photoelectron can exceed the level of noise of amplifier however the fluctuations of multiplication factor in APD do not make it possible to register the light pulses which contain less than 20-50 photonsTo increase the multiplication factor of traditional silica APD to 104 or more is impossible for the thermal breakdown of p-n- junction and the failure of instrumentHowever the way has been found allowing to increase amplification It is a creation of structure in which the avalanche discharge is limited to a feedback mechanism Works in this direction to Russia were spent at Physical institute of PNLebedev of the Russian Academy of Sciences where the structure of type metal-dielectric-semiconductor (MDS)] was investigated In such structures carriers appearing during an avalanche collect on border has undressed the semiconductor-dielectric that leads to local decrease in intensity of electric field reduction of factors of shock ionization and the termination of formation of an avalanche mode

The basic lacks of MDP-structures - necessity of giving the pulse voltage power supply and degradation of characteristics of the device
Problems have been solved at use of structures metal-resistive a layer-semiconductor (MRS) It has allowed to increase essentially factor of strengthening of a photocurrent (to 104) to improve stability of characteristics to increase the area of a sensitive surface and service life of devices
bullSimultaneously in a number of world laboratories possibility of application for registration of single photons of the p-n-junction working in an avalanche mode at voltage above breakdown was studied ie in a Geiger mode Geiger Such detectors named SPAD (Single Photon Avalanche Diode) are capable to register single photons with efficiency to 80 In Geiger mode the signal from one photon arriving on 50 Ohm loading can make some volt

Pulse height spectrum of weaklight flashes measured with a G-APD
This device can detect single photons like a PMT and therefore some people call it Silicon PhotoMultiplier SiPM The pulse height spectrum measured with a G-APD shows a resolution which is even better than what can be achieved with a photomultiplier and even with a hybrid photomultiplier tube
GOMEL09 July 15-26 FZiaziula 22
SiPM what is itThe MRS (Metal-Resistor-Silicon) structure SiPM (Silicon PhotoMultiplier) is a new type of Geiger-mode avalanche photodiode that shows promise for use with scintillators They have recently been tested as possible detectors for the hadron calorimeter tiles for the next-generation International Linear Collider The SiPM is a p-n junction diode that is biased above the breakdown voltage in order to create a Geiger avalanche Structure of the micropixel of a SiPM
The resulting depletion region in this device is of the order of just 5microm
with an avalanche region of around 1microm Such a thickness is sufficient for
optical photon detection The Geiger avalanche is passively quenched by
a resistive load in series with the diode In the MRS structure of this
SiPM the resistive load takes the form of a special technology layer
deposited on the diode surface

SiPMT is a photodetector on the basis of the ordered set (matrix) of the p-n-junction (cells) executed on the general substrate The characteristic size of a cell is an order 30-100 microns Density of packing of a matrix - about 100-1000 cellsmm2 The area of the sensitive surface SiPMT may lays in limits from 1times1 to 5times5 mm2 and more All cells are identical All of them are united in the general point by current-carrying bus Displacement voltage of all cells the general It on some volts (value of an overvoltage) exceeds voltage of breakdown of p-n junction Each cell contains current-limiting resistor Therefore Geiger breakdown current in a cell is limited The signal of each cell - logic also does not depend on number of the initial carriers which have caused operation of a cell
SiPMT itself as whole represents the analogue detector as its output signal is equal to the sum ofidentical signals of the p-n junctions which have operated at absorption by them of photons

The energy resolution of CMS ECAL meets the design goal for the detector For uniform illumination of a crystal with 120 GeV electrons a resolution of 05 was achieved
The avalanche photodiode (APD) developed for the electromagnetic calorimeter of CMS has a thin p-doped layer of silicon in front of the p-n junction where the photo conversion takes place The created electrons are amplified The internal gain of an APD improves the signal to noise ratio but the excess noise factor (avalanche fluctuations) and the gain sensitivity to voltage and temperature variations contribute to the energy resolution

SOLID STATE DETECTORSThe main disadvantages which impede use PMT in some specific applications are large sizes the high voltage of power supply and sensitivity to the magnetic fields Furthermore during the construction of the systems which contain hundred thousand channels of registration important factor becomes the price of detector which in the case PMT is sufficiently highThese factors became the reason for the active development of the solid-state instruments which use a phenomenon of the photoconductive effect The semiconductor detectors of photons can be divided into two large groups the photodetectors in which the transformation of light signal occurs bullwithout the internal amplification of chargebull photodetectors with the internal amplification of charge The first group includes the p-i-n photodiodes which because of their reliability compactness and low cost successfully adapt in different physical experimentsThe quantum effectiveness of these photodiodes in the maximum of spectral sensitivity reaches 90

However with light recording of the short duration (less than 1 μs) it is necessary to use the external wideband amplifier whose noise does not make it possible to register the flash of light with the number of photons of less than 1000 Furthermore relatively great thickness of the depletion layer makes p-i-n photodiodes sensitive to others emissions (gamma-quanta the charged particles)

In the detectors of the second group the internal amplification of charge occurs as a rule due to the impact ionization of carriers in the high electric fields Under the action of field free charge carrier (electron or hole) obtain energy sufficient for the ionization of neutral atom and release one additional electron hole pair this process can be repeated repeatedly Semiconductor detectors with the internal strengthening of charge caused by impact ionization avalanche photodiodes (APD) ) were developed more than 50 years agoMerits of APD - high speed operation and quantum effectiveness (to 90) and also broad dynamic band Mu-factor of the industrial standards of silica APD which work in the proportional regime (ie with the signal at the output APD proportional to the intensity of recorded light) comprises ~102
Thus to record single photons by the traditional detectors on the basis of p-n junction which workin the proportional regime of amplification is impossible

Special technologies make it possible to make APD with the mu-factor to ~103 With this mu-factor the signal from the single photoelectron can exceed the level of noise of amplifier however the fluctuations of multiplication factor in APD do not make it possible to register the light pulses which contain less than 20-50 photonsTo increase the multiplication factor of traditional silica APD to 104 or more is impossible for the thermal breakdown of p-n- junction and the failure of instrumentHowever the way has been found allowing to increase amplification It is a creation of structure in which the avalanche discharge is limited to a feedback mechanism Works in this direction to Russia were spent at Physical institute of PNLebedev of the Russian Academy of Sciences where the structure of type metal-dielectric-semiconductor (MDS)] was investigated In such structures carriers appearing during an avalanche collect on border has undressed the semiconductor-dielectric that leads to local decrease in intensity of electric field reduction of factors of shock ionization and the termination of formation of an avalanche mode

Problems have been solved at use of structures metal-resistive a layer-semiconductor (MRS) It has allowed to increase essentially factor of strengthening of a photocurrent (to 104) to improve stability of characteristics to increase the area of a sensitive surface and service life of devices
bullSimultaneously in a number of world laboratories possibility of application for registration of single photons of the p-n-junction working in an avalanche mode at voltage above breakdown was studied ie in a Geiger mode Geiger Such detectors named SPAD (Single Photon Avalanche Diode) are capable to register single photons with efficiency to 80 In Geiger mode the signal from one photon arriving on 50 Ohm loading can make some volt

SiPM what is itThe MRS (Metal-Resistor-Silicon) structure SiPM (Silicon PhotoMultiplier) is a new type of Geiger-mode avalanche photodiode that shows promise for use with scintillators They have recently been tested as possible detectors for the hadron calorimeter tiles for the next-generation International Linear Collider The SiPM is a p-n junction diode that is biased above the breakdown voltage in order to create a Geiger avalanche Structure of the micropixel of a SiPM
The resulting depletion region in this device is of the order of just 5microm
with an avalanche region of around 1microm Such a thickness is sufficient for
optical photon detection The Geiger avalanche is passively quenched by
a resistive load in series with the diode In the MRS structure of this
SiPM the resistive load takes the form of a special technology layer
deposited on the diode surface

SiPMT is a photodetector on the basis of the ordered set (matrix) of the p-n-junction (cells) executed on the general substrate The characteristic size of a cell is an order 30-100 microns Density of packing of a matrix - about 100-1000 cellsmm2 The area of the sensitive surface SiPMT may lays in limits from 1times1 to 5times5 mm2 and more All cells are identical All of them are united in the general point by current-carrying bus Displacement voltage of all cells the general It on some volts (value of an overvoltage) exceeds voltage of breakdown of p-n junction Each cell contains current-limiting resistor Therefore Geiger breakdown current in a cell is limited The signal of each cell - logic also does not depend on number of the initial carriers which have caused operation of a cell

SiPM what is itThe MRS (Metal-Resistor-Silicon) structure SiPM (Silicon PhotoMultiplier) is a new type of Geiger-mode avalanche photodiode that shows promise for use with scintillators They have recently been tested as possible detectors for the hadron calorimeter tiles for the next-generation International Linear Collider The SiPM is a p-n junction diode that is biased above the breakdown voltage in order to create a Geiger avalanche Structure of the micropixel of a SiPM
The resulting depletion region in this device is of the order of just 5microm
with an avalanche region of around 1microm Such a thickness is sufficient for
optical photon detection The Geiger avalanche is passively quenched by
a resistive load in series with the diode In the MRS structure of this
SiPM the resistive load takes the form of a special technology layer
deposited on the diode surface

SiPMT is a photodetector on the basis of the ordered set (matrix) of the p-n-junction (cells) executed on the general substrate The characteristic size of a cell is an order 30-100 microns Density of packing of a matrix - about 100-1000 cellsmm2 The area of the sensitive surface SiPMT may lays in limits from 1times1 to 5times5 mm2 and more All cells are identical All of them are united in the general point by current-carrying bus Displacement voltage of all cells the general It on some volts (value of an overvoltage) exceeds voltage of breakdown of p-n junction Each cell contains current-limiting resistor Therefore Geiger breakdown current in a cell is limited The signal of each cell - logic also does not depend on number of the initial carriers which have caused operation of a cell
SiPMT itself as whole represents the analogue detector as its output signal is equal to the sum ofidentical signals of the p-n junctions which have operated at absorption by them of photons

The energy resolution of CMS ECAL meets the design goal for the detector For uniform illumination of a crystal with 120 GeV electrons a resolution of 05 was achieved
The avalanche photodiode (APD) developed for the electromagnetic calorimeter of CMS has a thin p-doped layer of silicon in front of the p-n junction where the photo conversion takes place The created electrons are amplified The internal gain of an APD improves the signal to noise ratio but the excess noise factor (avalanche fluctuations) and the gain sensitivity to voltage and temperature variations contribute to the energy resolution

SiPM what is itThe MRS (Metal-Resistor-Silicon) structure SiPM (Silicon PhotoMultiplier) is a new type of Geiger-mode avalanche photodiode that shows promise for use with scintillators They have recently been tested as possible detectors for the hadron calorimeter tiles for the next-generation International Linear Collider The SiPM is a p-n junction diode that is biased above the breakdown voltage in order to create a Geiger avalanche Structure of the micropixel of a SiPM
The resulting depletion region in this device is of the order of just 5microm
with an avalanche region of around 1microm Such a thickness is sufficient for
optical photon detection The Geiger avalanche is passively quenched by
a resistive load in series with the diode In the MRS structure of this
SiPM the resistive load takes the form of a special technology layer
deposited on the diode surface

SiPMT is a photodetector on the basis of the ordered set (matrix) of the p-n-junction (cells) executed on the general substrate The characteristic size of a cell is an order 30-100 microns Density of packing of a matrix - about 100-1000 cellsmm2 The area of the sensitive surface SiPMT may lays in limits from 1times1 to 5times5 mm2 and more All cells are identical All of them are united in the general point by current-carrying bus Displacement voltage of all cells the general It on some volts (value of an overvoltage) exceeds voltage of breakdown of p-n junction Each cell contains current-limiting resistor Therefore Geiger breakdown current in a cell is limited The signal of each cell - logic also does not depend on number of the initial carriers which have caused operation of a cell
SiPMT itself as whole represents the analogue detector as its output signal is equal to the sum ofidentical signals of the p-n junctions which have operated at absorption by them of photons
