Concept of a compact high-resolution neutron spectrometer based on GEM detector for fusion plasmas

Abstract

Abstract In this paper, the conceptual design and operational principle of a novel TPR neutron spectrometer based on GEM, intended for future spectrometry applications dedicated to fusion plasmas, is described. A feasibility study based on theoretical modelling and computer simulations of a possible detector configuration prototype is presented. In particular, we discuss the results of optimizing the detector geometry, estimating its overall performance, and the expected quality of energy resolution.
