Novel LaCl(Ce)-based spectrometer for deuterium plasma neutron diagnostics.

This work studies in detail the application possibility of a chlorine-based cerium-doped scintillator crystal [LaCl(Ce)] to the task of D-D neutron spectrometry. We conducted an experimental campaign aimed at deriving the optimal setup parameters and energy calibration using a variety of available neutrons and γ-sources. The GEANT4 code was used for modeling the detector response to γ-ray irradiation.
