Paper Abstract

We have analysed the tracks left by cosmic-ray particles on the CCDs of the EPIC-MOS cameras onboard XMM-Newton. These tracks could be entirely visualized by using a special operation test mode, and their characterization could be performed. This has allowed to measure the cosmic-ray flux at the level of the focal plane, as well as the fraction of the CCD surface which is sterilized by the cosmic-ray impacts. The relation between this fraction and parameters transmitted to the ground during normal observations has been established.
