The adopted solutions involve Monte Carlo simulation by both Geant4 toolkit related to the "expected" background at L2 orbit through the payload mass model and the ray tracing technique to evaluate the soft protons components focussed by the optics to the main detector, and the development of an active Cryogenic AntiCoincidence detector and a passive electron shielding to meet the scientific requirements. <P /> | Conference Name: | Exploring the Hot and Energetic Universe: The first scientific conference dedicated to the Athena X-ray observatory. | Conference Place: | Madrid, Spain | Conference Date: | 8-10 September, 2015 | URI: | http://hdl.handle.net/20.500.12386/23601 | URL: | https://www.cosmos.esa.int/web/conferences-archive/athena-2015 | Bibcode ADS: | 2015eheu.conf...72M | Fulltext: | open |
