The PANDA experiment at the upcoming FAIR accelerator facility will study antiproton annihilation reactions at antiproton beam momenta from 1.5 GeV/c up to 15 GeV/c. With its modular multi purpose detector system it will be able to observe a variety of physical channels. The electromagnetic process group (EMP) in Mainz is developing the Backward-End-Cap (BWEC) of the electromagnetic calorimeter. A prototype calorimeter, PROTO16, has been developed to improve different components of the BWEC. PROTO16 employs a very realistic setup as in the BWEC such as cooling, insulation and signal processing. In addition, PROTO16 is equipped with a proper slow control, which is capable of controlling and reading out all relevant components of the detector. During three different test beamtimes at the MAMI (Mainzer Mikrotron), the prototype properties have been intensely studied and improved. An energy resolution of 2,5% at 1GeV and a lowest single threshold of 3MeV has been achieved. Our poster explains the main features of the PANDA -calorimeter and provides information about the latest analysis results for the PROTO16 test with electron beam.
