GEANT simulation of the AGILE gamma-ray imaging detector
Abstract
We present results obtained with a GEANT-based Simulator of the Gamma-Ray Imaging Detector (GRID) developed for the AGILE space astrophysics mission. We describe the AGILE instrument geometry and the model assumed for the charged particle and the albedo-photon backgrounds. Using this simulator, we optimized the event trigger processing. In this paper, we present the main results on different levels of data processing and obtain the background rejection efficiency and the GRID effective area for photon detection in the energy range ~30 MeV-50 GeV. .
