Each PMT will have a high voltage cable and a signal cable. HV cables will be fed by a CAEN SY2527 Power Supply. Signal cables will terminate at a patch panel in the data acquisition racks. A pretrigger history of at least 1 ms and a posttrigger history of at least 100 us must be kept for all veto counters on each event. The function of the conditioner boards is to route any combination of detector trigger signals from the RTF P2 backplane to the history buffer and trigger logic.
Inputs come from the trigger conditioners, veto, random pulser, and front-end trigger.
Global OR of selected detector triggers 2. Any particular detector trigger can be turned off if desired. All of these choices should have readback latches so one can easily determine the state of the trigger logic. The board can also form a detector readout mask based on the trigger bits. Note that use of selective readout and trigger rejection based on energy thresholds should allow an order of magnitude reduction in data flow requirements during calibration.
