Abstract

Liquid organic scintillators used for neutron spectrometry must be employed with pulse shape discrimination against gamma radiation. As the dimensions of the spectrometer are increased, the uniformity and the n-γ discrimination properties of the spectrometer deteriorate while its efficiency increases. The properties of a NE-213 liquid scintillator of a parallelepiped shape are investigated with respect to the spectrometer length. For the geometry of a point source near the spectrometer wall, it is estimated that a spectrometer of a length of 10-15 cm will display optimal performance.
