Abstract :
A single width D sized VXI card has been designed and built to fully instrument one of the new Clover detectors designed for experiments with the EUROGAM array. Each Clover detector consists of 4 individual germanium (Ge) crystals and an escape suppression shield comprising 16 bismuth germanate (BGO) crystals. The Clover electronics card measures energy and timing data to 13 bit accuracy from each Ge crystal for spectroscopy and measures sum energy and timing for the BGO shield. It also records a complete Ge and BGO hit pattern for each event and performs intelligent hardware escape suppression to exploit the segmented nature of the Clover detectors
