Predictions of radiation backgrounds for GRO/OSSE
Abstract
In view of the important influence of background radiation induced by the charged particle environment on the sensivity of spaceborne gamma ray instrumentation, an extensive series of simulations was performed on representations of the Oriented Scintillation Spectrometer Experiment (OSSE) and Gamma Ray Observatory (GRO) spacecraft. Previously reported results on shielding are summarized and new results are presented on the influence of detector and spacecraft orientation within anisotropic trapped proton distributions. For the cosmic ray calculation, confidence is obtained by comparison with background observations obtained during a balloon flight of a single detector unit over Alice Springs, Australia.
