ELECTRONICS FOR RADIATION DETECTION. 2. DISCRIMINATRO AND ALLIED CIRCUITS
F.H. Wells · Nuclear Power · 1959
Some basic circuits for amplitude discriminators, including a cathode coupled univibrator, ihe d-c coupled trigger circuit with controlled paralysis time, circuits for dealing with very small and very fast input pulses, and a transistorized type for operating on current pulses are reviewed. It is shown how two amplitude discriminators followed by gating circuits are used to form a single channel pulse amplitude analyser and how refinements for stable narrow channel and accurate timing applications are made. After reviewing a Geiger Mueller quench circuit, a description of the principles of coincidence and anti- coincidence circuits as far as two channel slow circuits and a typical coincidence pulse shaping circuit and mixer are given.
