Si Sensors for ECAL (V. Vrba)

Sensor ECAL prototype production: 2006: in four production runs of Si pad sensors at ON

Semiconductor we obtained 72 good fully tested wafers which have been integrated into ECAL prototype

January-July 2006: wafers delivered to Ecole Polytechnique 7 ECAL layers equipped with ON Semiconductor wafers

end of 2006: additional fabrication run at ON Semiconductor is planned to produce about 60 wafers for the full instrumentation for 2007 test beam.

Sensor testing @ Institute of Physics AS CR

Test laboratory for measurement of Si sensors

Senzors from ON Semiconductor, Czech Republic

EUDET tasks• Design studies for finer

granularity (5x5 mm2) of Si sensors are under way

• Possibility to use 6” wafers is also investigated


HCAL - Calibration + Monitoring Board system (I. Polák)

CMB provides calibrated UV flashes to the scintillator tiles optical feedback via PIN photodiode sensing of temperature at scintillator planes and

Our immediate tasks in EUDET Production of Si wafers for ECAL module successfully integrated

into the prototype and operated in the test beam Design studies for finer granularity (5x5 mm2) of Si sensors are

under way; Possibility of the use of 6” wafers is investigated;

Students and young physicist (Petr Mikes, Michal Marcisovsky, Pavel Ruzicka, Miroslav Havranek) are involved in the project activities participating in the laboratory sensor evaluation, test beam runs at DESY and CERN, data analysis, simulation etc. They also participate in regular collaboration meetings.

HCAL – calibration electronics 2006: 40 (double) boards produced, 23 installed in the prototype,

one half financed from EUDET Investigations of functionality and long term stability of CMB
