In this work we report measurements of the Galactic diffuse continuum emission (GDCE) observed towards the inner Galaxy during the 2016 COSI Balloon flight, which in the COSI energy band ($0.2 - 5$ MeV) is primarily generated from inverse Compton radiation. Within …

We present measurements of electron and hole trapping in three COSI germanium cross-strip detectors. By characterizing the relative charge collection efficiency (CCE) as a function of interaction depth, we show that intrinsic trapping of both electrons and holes have significant effects on …

Abstract The Compton Spectrometer and Imager (COSI) is a balloon-borne compact Compton telescope designed to survey the 0.2–5 MeV sky. COSI’s energy resolution of ∼0.2% at 1.8 MeV, single-photon reconstruction, and wide field of view make it capable of studying astrophysical nuclear …
