Abstract

This paper will focus on next-generation inorganic scintillation detectors that could be used to study neutral emission from the high-energy Sun. Recent developments in detector technology have yielded candidate materials for future heliophysics missions, namely elpasolites (Cs2LiYCl6:Ce – CLYC and Cs2LiLaBr6:Ce – CLLB). At a modest cost, these detectors yield superior spectroscopic performance compared to previously used materials (NaI:Tl and CsI:Tl). Additionally, elpasolites can detect and measure thermal to fast (<10 MeV) neutrons, simultaneously with γ rays. In the following sections, we discuss: the importance for measuring neutral emission from the Sun, laboratory performance of candidate scintillators and novel light readout devices, a proposed instrument concept, and the expected response to a γ-ray line-producing and neutron-producing solar flares from the vantage points of 1 AU, 0.3 AU, and 0.04 AU.
