The characteristics of a Li-glass scintillation detector have been studied in order to determine an optimum design for a neutron time-of-flaght detector for use in hlgh resolution total crosssection measurements. A light- tight box was used for comparative tests of light collection geometry fur the Li- glass scintillator on a fast photomultiplier. Effectave discrimlnation against gamma -background is shown to be dependent on a knowledge of the nature of the sclntillator pulses. This also determines the system required to achieve the best timing resolution. A simple test circuit is described whlch makes it possible to set up or reset the timing system and the important discrimination levels using a /sup 60/Co gamma -source. A time resolution of 3.4 ns (fwhm) was measured for the Li-glass detector. The application of the detector to the time- of-flight spectrometer is discussed together with measurements of the resolution and the neutron energy spectrum. (auth)
