摘要

A pulse‐shape discrimination system for use with organic scintillators is described which is based upon the true zero‐crossing detection of single delay‐line shaped pulses. Results of performance tests are presented in the form of contour diagrams which show the crossover‐time spectra of neutron and gamma‐ray induced events as a function of pulse amplitude. A technique to compensate for the variation of scintillation pulse shape with recoil‐proton energy is described. Good gamma‐ray rejection with nearly 100% recoil‐proton acceptance over a dynamic range of 100 is obtained.
