Abstract :
The TIGRESS spectrometer is an array of escape suppressed, highly segmented, HPGe clover detectors, consisting of 896 channels, with around 1000 auxiliary detector channels available. The acquisition system is all digital, each detector signal is digitized and any filtering and subsequent processing is performed digitally. The system has been designed to integrate data flow, clock distribution, trigger, and acquisition control through the same serial links. A hierarchical trigger system is implemented, allowing various combinations of incoming trigger requests to be decided locally, or passed to any of the higher levels for final decision.
