A pulse shape discriminator is described, which is designed to permit detection of low energy neutrons in the presence of a very high gamma -ray background at high counting rates. An improvement is obtained by using a fast crystal diode switch for the separation of the fast and slow parts of the scintillator de-excitation pulse. This device greatly reduces interference effects from nearly coincident de tector pulses, and also permits better pulse matching and comparison. The best discrimination is obtained for moderate sensitivity and counting rates, where out of 10/sup 5/ detected gamma rays about one is erroneously admitted. A description of the circuit and accessories is given, and results of test runs at a 20 Mev FM cyclotron are presented. (auth)
