Response of a close to final prototype for the View the MathML sourceP¯ANDA Electromagnetic Calorimeter to photons at energies below 1 GeV

The response of two generations of prototypes of the View the MathML sourceP¯ANDA Electromagnetic Calorimeter (EMC), PROTO60 and PROT120, to photons in the energy range between 50 MeV and 800 MeV was obtained. Furthermore, the performance of the pre-amplifier ASIC (APFEL) under real experimental conditions, the position dependence of the energy resolution within the crystal and the implementation of higher order energy correction algorithms with a 15 GeV/c positron beam were studied.
