Beam Test Plansat the KEK Fuji Beam line

(as of Nov-7 2007)

S. Uozumi

In this slide I will give my idea for somewhatdetailed beam test plan.Let’s discuss and finalize it !

Good and not-so-bad news

• We can borrow the ATLAS SCT

(Thanks to Hara-sensei) ! One undergrad student working on SCT in Tsukuba will finish his grad thesis with

SCT data which will be taken in our BT.

• The SCT can be operated only through Windows PC.

Therefore we have to take all the data with Windows PC this time (the PC can be borrowed from Tsukuba).

• We can also borrow X-Z movable stage from ATLAS

(thanks to Kohriki-san and Ikegami-san), but it may be difficult to link the stage movement with our DAQ system.

Need to perform hand-input scan ?

• “start” means start of preparation, Nov-12 on Monday.• “end” means the date where everything is done (includes possible delays).• Let me know if there are modifications needed on the participating period.

Overall schedule~Nov-12th: Gather equipments at KEK

Nov 12th~24th : Start preparation of DAQ, SCT and SciFi system at Fuji B4 by people who can participate.

Nov 16th : Almost participants are at KEK, take radiation training and have a kick-off meeting.

Nov 17th,18th (weekend) : Prepare everything as much as possible

Nov 19th~20th : Beamtime starts, setup on beamline

Nov 20th ~ 24th : As soon as the setup finished, start comissioning run followed by strip scan and run as long as possible

Nov 25th : end of the beamtime (could be extended) , withdraw from beamline

Scintillator-strip assembly

spacer

• As done at the DESY BT, strips will be mounted in acrylic frame, and the scintillator layers will be installed in the detector frame and light shielded.

• To all the MPPC, uniform bias voltage will be applied by source meter.• Signal from MPPCs will be read by CAMAC ADC after signal amplification by ATLAS ASD.

Frame

Operation / Readout electronics

• Scintillator strips … MPPCs are biased by source meter, signal will be amplified by ATLAS ASD and read with CAMAC ADC.• Trigger / veto counters … read with CAMAC ADC.• SciFi tracker … (amp+) discri + CAMAC coincidence register.• SCT … need dedicated VME modules and software.• Movable stage … need dedicated system.• Temperature sensor … can be read by Windows PC ?

Strips to be tested- Let’s start with newer stuff, since beam time and rate are limited -

1. Extruded 3 mm thick direct readout without TiO2

2. Extruded 3 mm thick fiber EMBEDDED readout with TiO2

3. Extruded 3 mm thick fiber EMBEDDED readout without TiO2

4. Extruded 3 mm thick fiber readout with TiO2

5. Extruded 3 mm thick direct readout with TiO2

6. Extruded 3 mm thick fiber readout without TiO2

7. Kuraray strip 3 mm thick fiber readout8. Kuraray strip 3 mm thick direct readout9. Kuraray strip 2 mm thick direct readout

Old ones

Newly produced

Kuraray as Reference

• Will start with (1~3)+7 with ~3 different strips, and if time permits test 9, 8 and 4, and if time permits we will test 9, 8 and 4~5.• Use the same MPPCs if possible, for direct comparison.• Detailed plan will be finalized at kick-off and on-shift meeting.

Run Plan and DAQ Time Estimation

• Assume ~1000 events / mm2 (is it enough?)• 10 x 45 x 1000 = 450000 events per a strip• 450k events / 10 (30) Hz = 750 (250) min per a strip• Random trigger run ~ 5 min, taken once per an hour• 12~13 (4~5) hours to scan one strip.• Perform multiple (2~3) layers scan.• Configuration change ~ 2 hours (?)

Need to take data with MIP position scan andRandom trigger (pedestal and MPPC gain by dark noise)With each type of scintillator.

Red numbers … estimation with the SCT

Data Monitoring & Analysis

• We will perform “on-the-fly” analysis during data taking.• Need always to watch gain (by pedestal run), light yield, and position dependence for all the strips on bea

mline.• Better to plot the temperature, too.• The analysis will run on Linux PC.

Startup jobs• DAQ system and Electronics (1 staff+1 student)

– Operation of CAMAC, SCT, temperature monitoring system and movable stage.– Manage trigger logic and electronics.

• Beamline devices (1+3)– Maintain trigger, veto, SciFi, SCT hardware– Installation (need to make support frames), cabling, alignment, HV, s

etting threshold and timing.• Detector + movable stage (1+1~2)

– Assemble scintillator-strip module, alignment, connection, cabling.– Check signal by beta-ray source– Detector and movable stage installation on beamline– Install temprature monitoring sensors at the same time.

• Analysis codes (0~1 + 0~1)– Discuss data format with DAQ team– Prepare root macro for “on-the-fly” analysis

Shift plan

• 3 shifts per a day (0~8, 8~16, 16~24), 2~3 persons (at least 1 staff + students) in one shift.• Official language is English during the beam test ! To share all the information, DO NOT use Japanese as possible as you can !• Contact me anytime (Satoru : 080-3500-8846) if you have any trouble during your shift.

Radiation training / accommodation

• Make registration as KEK rad-worker ASAP via the KEK web site! ( http://www.kek.jp/uskek/ )

• In addition to the rad training at KEK, beamline lecture will be needed.

I will ask KEK person to give a lecture on Oct-16 (Fri).• For accommodation, you have to make the KEK dorm re

servation by yourselves!• Unfortunately dormitory is already full for some dates (No

v-13,14,19,20..), but you can join to waiting list.• After the reservation, let me know which date you couldn’

t take the room, then I will try to find another accomodation for those days.

• Let me know if you have any questions.

Is there anything missing?

Stripscintillators

• Analog signal from trigger and veto counters will be useful to reject shower events.• X-Y tracking by SciFi detector (by 1mm scintillating fibers).• Since there is only 1 X-Y tracker available, the tracker should be as close as possible to the strip scintillators.• Strips will be mounted in the frame used at the DESY BT.• Target strips will be placed on 1st layer, latter layers may be used for offline MIP selection.

Memo (just not to forget)
