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.

14. 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
Participation in tests and data analysis
