Abstract

A GAGG detector capable of dissecting a multi-coincidence solar neutrino interaction on 71Ga is under development for potential space-based applications. We identify three distinct detection signatures when 71Ge∗ is produced, two of which are significantly delayed in time and could be detected within a single large GAGG volume. Further optimizations can be made by optically isolating smaller segments of GAGG to maximize the probability of a spatial separation between the prompt/delayed signals. We construct and test prototype GAGG detectors capable of a sub 7% energy resolution @ 137Cs and reliable detection of spatially-separated 57Co double-pulse decays. © 2025 Elsevier B.V.
