Low-angle scattering of protons on the XMM-Newton optics and effects on the on-board CCD detectors

Evans, H.; Nieminen, P.; Daly, E. +3 more

Monte Carlo simulations are presented where protons are shown to propagate through X-ray telescope optics by grazing incidence scattering processes. If these protons reach charge coupled device (CCD) detectors in sufficient numbers, they can induce a radiation background, and at certain energies, the nonionising dose can cause degradation of the c…
