Abstract :
Electronics for six EUROGAM BGO shields is integrated onto one VXI (VME extension for instrumentation) D-size module. For each of the six shields, time and energy measurements are processed. As each shield consists of 10 BGO detectors, a ´hit´ pattern of the BGO detectors is also built. The output of the very-low-energy discriminator for the anti-Compton shield is transmitted, via the VXI local bus lines, to the corresponding Ge channel in the neighboring VXI module to allow fast suppression to take place.<>
