A VXIbus based trigger for the CLAS detector at CEBAF

A VXIbus based first level triggering system for the CLAS detector at CEBAF has been designed and prototyped. It uses pipelining and a triple memory lookup to produce a dead-timeless trigger decision with an average latency of 110 nS and a jitter of 20 nS. The VXIbus Extended Start/Stop triggering p...

Zusammenfassung:	A VXIbus based first level triggering system for the CLAS detector at CEBAF has been designed and prototyped. It uses pipelining and a triple memory lookup to produce a dead-timeless trigger decision with an average latency of 110 nS and a jitter of 20 nS. The VXIbus Extended Start/Stop triggering protocols allow sub-nanosecond time synchronization.
