Crystal scintillators for the PANDA electromagnetic calorimeter — •Bernd Lewandowski — Inst. f. Experimental Physics I - Ruhr-University Bochum

PANDA is a 4π detector planned for the antiproton storage ring at the proposed International Accelerator Facility for Beams of Ions and Antiprotons at the GSI. Experiments forseen with the antiproton beam of extremely high luminosity and excellent beam quality up to 15 GeV/c beam momentum require an electromagnetic calorimeter of high granularity and resolution to measure photons of several GeV down to 10 MeV energy. The scintillator materials being investigated for this calorimeter are BGO and new improved PbWO₄ crystals. First results of testbeam measurements with protons at KVI/Groningen are presented.
