摘要：

The methods of obtaining the parameters of the full absorption neutron spectrometer constructed in JINR [V.P. Dzhelepov et al., Nucl. Instr. and Meth. A269 (1988) 634] (full scintillator volume V=24 1) and used in experiments studying the muon catalysis process are considered. These parameters have been obtained from the analysis of pulse-height distributions measured with γ-sources of different energies and with neutrons selected from the 238PuBe spectrum using the TOF method. A value of σFWHM=0.09(1+ 1 √Ee(MeV) has been obtained for the pulse-height resolution. It is two times better than that obtained for a detector [G. Dietze and H. Klein, Nucl. Instr. and Meth. 193 (1982) 549] of smaller size. The threshold energy for n-γ separation Eγthr≅50keV, which corresponds to the best results obtained with small detectors. © 1990.
