Experimental Investigation on the Limits of Time Resolution of Scintillation Counters

Abstract

The widths of the time‐resolution curves of scintillation counters (Philips 56 AVP, plastic, and stilbene scintillators) are measured as a function of the height at which the timing pulse is derived from the rising edge of the scintillation pulse. A very small fraction of this leading edge is used to create a timing signal in a biased two‐stage limiter circuit. The arrangement agrees closely with a timing method discussed by Gatti and Svelto and the results are compared to their theoretical predictions.
