Transverse BGO Compton suppression shield

The performance of a Compton suppressed Ge spectrometer, that utilizes a transverse BGO suppression shield, is presented. A comparison of the experimental measurements and Monte Carlo calculations is made.

A versatile electronic pulse-shape discriminator

Abstract 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 discrimination or with NaI(Tl) detectors for charged particle identification. Variations of the circuit which minimize either the power consumption or the complexity are presented. Outputs are provided for either a charge-to-digital converter or a time-to-digital converter.

A single element NaI(Tl) light particle detector

Abstract The feasibility of resolving protons, deuterons, tritons, and alpha particles over a large energy range with a single NaI(Tl) scintillator is demonstrated. This is accomplished by combining light output, time-of-flight, and pulse shape information.
