Abstract
Fast neutron spectrometers with high energy resolution are required in some research fields such as nuclear physics and thermo-nuclear fusion plasma diagnostics. In this study, a fast neutron spectrometer based on GEM-TPC has been proposed, which uses the energy of recoiled protons and the recoil angles from reconstructed proton tracks to derive the neutron energy. Compared to the traditional spectrometers, this new method has merits such as high detection efficiency and excellent discrimination ability for neutron from gamma.
