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.
