A systematic analysis of the XMM-Newton background: IV. Origin of the unfocused and focused components

Abstract

We show the results obtained in the FP7 European program EXTraS and in the ESA R&D ATHENA activity AREMBES aimed at a deeper understanding of the XMM-Newton background to better design the ATHENA mission. Thanks to an analysis of the full EPIC archive coupled to the information obtained by the Radiation Monitor we show the cosmic ray origin of the unfocused particle background and its anti-correlation with the solar activity. We show the first results of the effort to obtain informations about the particle component of the soft proton focused background.

To appear in Experimental Astronomy. Presented ad AHEAD Background Workshop, 28-30 November 2016, Rome, Italy
