Photo sensors for the PANDA electromagnetic calorimeter — •Andrea Wilms — Inst. f. Experimental Physics I - Ruhr-University Bochum

The Experiments planned for the PANDA 4π detector at the future antiproton facility of GSI require an electromagnetic calorimeter of high granularity and resolution to measure photons of several GeV down to 10 MeV energy. The choice of a suitable photo sensor for the detection of the scintillation light is crucial to achieve the best possible energy resolution. The CMS ECAL group and Hamamatsu have invested huge efforts in the development of extremely reliable and robust large area Avalanche Photo Diodes (APDs). This experience makes these APDs a natural choice for the start of the R&D program. First results of testbeam measurements with protons at KVI/Groningen are presented.
