Detector Performance of the Moon Burst Energetics All-sky Monitor

Moon Burst Energetics All-sky Monitor (MoonBEAM) is a gamma-ray mission in a cislunar orbit to observe the entire sky instantaneously for relativistic astrophysical explosions. It is designed to explore the behavior of matter and energy under extreme conditions by observing the prompt emission from gamma-ray bursts, identifying the conditions capable of launching transient relativistic jets and the origins of high-energy radiation from the relativistic outflows. MoonBEAM utilizes a set of 6 phoswhich detectors to achieve all-sky nearly continuous coverage. The phoswich design allows for dual mode observations, for localization and a wide spectral coverage. In this talk I will discuss the initial calibration and lab validation on the detectors utilizing different radioactive sources.
