Abstract

We investigate the proton fluence and particle background for the Micro-Channel-Plate X-ray Telescope (MXT) instrument aboard the SVOM satellite, to be placed in a Low Earth Orbit (LEO) at ~600 km altitude and ~30° inclination. The adopted detector at the focal plane is a pn-CCD similar to that used on eROSITA. Monte-Carlo simulations aim at identifying and comparing different possible solutions for the design of the MXT focal plane, in order to conveniently reduce possible radiation damages and the particle induced background. We give here a description of the LEO radiation environment, and present some results of particle background simulations referring to the present baseline configuration.
