A 128-channel microstrip Germanium detector for Compton scattering experiments at the SPring-8 facility

A 128-channel microstrip Germanium detector system has been developed to efficiently detect Compton-scattered X-rays and to effectively reject the background X-rays associated in the Compton spectrometer of the high-energy inelastic scattering beamline at the SPring-8 facility. In order to handle the large number of the readout channels, four 32-parallel-input front-end hybrid boards have been adopted as charge-sensitive pre-amplifiers and discriminators, which are currently controlled by a Windows-based PC data-acquisition system.
