Abstract :
The multi-channel photomultiplier (Philips XP1702) can be utilized as a high resolution area detector for thermal neutrons and high energy gamma rays. This detector type is needed e.g. for special neutron scattering experiments and for the PET method applied to small animals. In various test measurements this will be demonstrated by coupling suitable scintillators (NaI, BGO, and 6LiI single crystals and 6Li-glass) and dispersers to the photocathode and by feeding the 64 output signals of the PM into a resistor network via voltage-to-current converters
