Nuclear Instruments and Methods, 1961
Abstract Pulse shape discrimination methods used up to the present are discussed, considering in particular to what extent the possibilities offered by the shape of the scintillation decay are being exploited. A new method is then described which utilizes in a statistically optimum way and by simplest means the information obtainable from the various

A high speed pulse shape discriminator
Nuclear Instruments and Methods, 1970Abstract A high speed pulse shape discriminator utilizing the true zero crossover technique is described. Tunnel diodes are used in leading edge “anti-walk” timing and for zero crossover detection. The circuit has been used for n-γ discrimination applications with liquid scintillators and is demonstrated at rates above 8×10 4 cps.

A simple pulse-shape discrimination circuit
Nuclear Instruments and Methods, 1974Abstract A simple pulse-shape discrimination circuit is described. Some results are presented for NE213 organic liquid scintillators of different sizes. The influence of the lower threshold energy and the effect of high counting rates on the pulse-shape discrimination properties are shown.

Design of Mixed-mode Systems for Pulse-shape Discrimination
2021 IEEE International Midwest Symposium on Circuits and Systems (MWSCAS), 2021The use of a mixed-mode system for performing neutron/gamma (n/γ) pulse-shape discrimination (PSD) is investigated. Historically, PSD capable systems have been composed fully of analog electronics or use fast digitizers that allow for later analysis using digital signal processing (DSP).

Tunnel diode pulse shape discriminator
Nuclear Instruments and Methods, 1967Abstract A pulse shape discriminator is described which is suitable for neutron-gamma ray separation with several different detector types. It uses three tunnel diode discriminator circuits, one for setting an energy threshold, one for marking the leading edge setting an energy threshold, one for making the leading edge of the input signals and one ...

Pulse shape discrimination with a comparator circuit
Nuclear Instruments and Methods, 1970Abstract The pulse shape discriminator described employs an integrated circuit differential comparator to measure the zero cross-over time of a bi-polar pulse relative to the start of the pulse. The comparator element operates over a dynamic range of 0.02 to 10 V with a time shift of less than 4 ns for DDL pulses with a rise time of 100 ns. The pulse

Pulse Shape Discrimination in Stilbene Scintillators
Review of Scientific Instruments, 1961A simple, sensitive pulse shape discriminator is described, which was designed to permit detection of low energy neutrons in the presence of a very high γ-ray background, and at high counting rates. An improvement relative to discrimination circuits published so far was obtained by incorporating a fast crystal diode switch for the separation of the ...

Termination effect on pulse shape discrimination
2007 IEEE Nuclear Science Symposium Conference Record, 2007NE213 liquid scintillation detectors have been used in mixed radiation fields with great success due to their pulse shape discrimination (PSD) ability. Numerous PSD techniques using various analog equipments had been proposed and developed by various individuals in past years. A common method for PSD is to evaluate the fall-time of the voltage across a

Pulse Shape Discrimination in a Plastic Scintillator
IRE Transactions on Nuclear Science, 1960A plastic scintillator has been developed which shows a decay time dependent upon energy loss per unit distance, and hence is suitable for use with pulse shape discrimination methods. This scintillator was employed in conjunction with an improved discrimination system and the data were analyzed on a two-dimensional analyzer which provided a matrix of ...

A versatile electronic pulse-shape discriminator
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1989Abstract A pulse-shape discrimination circuit designed for use with multidetector arrays has been tested. Each module, containing two channels, occupies a single slot in a standard nuclear instrumentation module (NIM) crate and can be used without alteration, tests have shown, with either NE213 liquid scintillator detectors for neutron-gamma ray ...
