Abstract

A scintillation spectrometer with pulse shape separation of signals from neutrons and gamma quanta, installed on the RADEX neutron beam channel at the Institute for Nuclear Research is described. The need for n-γ separation is due to the presence of a substantial gamma background at the location of the spectrometer. To optimize n-γ separation, new parameters of the pulse shape separation and methods for calculating them are proposed. Significant improvement in the n-γ separation is obtained. Applying new parameters allows us to use information about only part of the scintillation pulse, enabling the operation of the spectrometer at high count rates and pulse pileup. Such a spectrometer can be used to monitor the RADEX neutron beam channel and determine the energy distribution of neutrons in the beam.
