Next generation of scintillation detector based on cerium bromide crystal for space application in the gamma-ray spectrometer of the Mercurian gamma-ray and neutron spectrometer

Abstract

A brief description is presented of the γ-ray spectrometer part of the Mercurian gamma-ray and neutron spectrometer (MGNS), the scientific instrument for planetary research on mapping of γ-ray and neutron emission from the Mercury surface onboard BepiColombo spacecraft of the European Space Agency (ESA) spacecraft. As the crystal for the γ-ray spectrometer, an innovative CeBr₃ scintillator was chosen on the basis of the ground tests and analysis of the results reported in this paper.
