Brooks, F D

A particle discriminator is described which involves the use ot two electrodes in a photomultiplier to produce two pulses for one scintillation. One pulse is ampiltudedependent, the other is amplitude- and duration-dependent. The difference pulse derived from them is submitted to an amplitude discriminator for selection. The pulse generation can be accomplished by a semiconductor and capacitor in a pulse stretching circuit, or by a shorted delay line for clipping one pulse. The derived pulse is prcduced in a pulse integrator. (T.R.H.)
