Abstract:

Organic scintillation detectors are useful for neutron spectroscopy because pulses induced by gamma rays and those induced by neutrons can be distinguished by electronic means. Computer analysis can be used to obtain the energy spectrum of the neutrons from the measured recoil-proton pulse-height distribution. The report describes a practical neutron spectrometer with improved electronic circuitry for pulseshape discrimination. A detailed study of the interaction of neutrons with the scintillator is presented in relation to pulse-height analysis. A computer program that uses a straightforward method of pulse-height analysis is given in FORTRAN with suggestions for adaptation for use on a small computer. Spectrometer applications are presented for measuring neutron spectra of monoenergetic neutrons, radioactive neutron sources, scattered neutrons and neutrons from a photonuclear reaction and also for detection of fission neutrons.
