STILBENE SPECTROMETER FOR NEUTRONS AND GAMMAS: ELECTRONICS AND RELATED PERFORMANCE,
Abstract
The instrumentation package of a spectrometer system for neutrons and gamma rays is discussed in detail. The pulse signals produced in stilbene crystal by neutrons and gamma rays are stored simultaneously in different memory subgroups of a multichannel analyzer by using pulse shape discrimination techniques. Neutrons in the energy range from 0.5 MeV to 20 MeV and gamma rays in the energy range from 0.15 MeV to 11 MeV are analyzed with a discrimination ratio exceeding 1000:1. The lower energy discrimination limit of the system is 22 keV electron energy which corresponds to 270 keV neutron energy and 90 keV gamma ray energy. (Author)
