A ‘when and where’ charged-particle sensing system

Abstract A prototype, eight-channel, integrated circuit is described which uses a 32-phase clock to record the arrival time of incident particles. The chip architecture is such that data can be acquired continuously to a pulse-pair resolution of 1 ns and up to a peak input frequency approaching 500 MHz per channel. The device incorporates cache memory and write only if data (WOID) techniques to maximize the throughput of the chip. A feedback circuit has been implemented in the delay line to ensure that the chip is immune to both temperature and voltage variations.
