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.
