NIM Module for installation in 5580A/B NIM PSU/rack

Coincidence detection systems, required in many nuclear experiments, separate for counting only those events which meet selected timing criteria. Anticoincidence detection suppresses the counting of events, such as cosmic rays, that generate pulses coincidentally in a guard detector and the primary detector.

The 5584A Dual Timing Pickoff generates fast pulses in response to nuclear detector outputs while providing appropriate delay for operation of a coincidence/anticoincidence system. Resolution is high: it's ready for the new input only 100nsec. after generating an output. Each channel responds to pulses of either polarity and generates both AEC fast logic (neg) and slow logic (pos) pulses. A new feature, you can select either leading-edge detection or detection of bipolar pulse zero-crossing. Sensitivity is adjustable:for leading-edge detection, 2mV-450mV; for zero-crossing, 50mV-750mV.
