Issues of Improving the Efficiency and Resolution of the Neutron Spectrometer for the National Center for Physics and Mathematics

Abstract

An analysis of the requirements for \((\gamma,n)\) experiments involving fast neutron spectrometry is provided for \(\gamma\)-ray energies in the E1 GR region; the parameters of collimated Compton radiation sources at HI\(\gamma\)S and the National Center for Physics and Mathematics (NCPM); the characteristics of the neutron spectrometer proposed for the NCPM; and the principles of one-dimensional time–coordinate compensation for neutron spectrometer scintillators. Initial experiments have been conducted to investigate the potential for improving the efficiency and resolution of such a spectrometer using the time–coordinate compensation method.
