Abstract :
A compact photon detector with nearly 4π-coverage in solid angle has been proposed to be implemented into the magnetic spectrometer ANKE at COSY, Julich. Based on the physics program and experimental constraints a first concept will be presented. As part of the R&D program, the response to monoenergetic photons between 45 and 770 MeV has been measured at the tagged photon facility at MAMI, Mainz for arrays consisting of large CeF3 and PbWO4 scintillation detectors. The applicability of a fine-mesh photomultiplier (Hamamatsu R5505) has been tested in static and variable magnetic fields
