Cooling out the radiation damage on the XMM-Newton EPIC MOS CCDs

Altieri, B.; Bennie, P. J.; Turner, M. J. L. +2 more

The X-ray astronomy satellite XMM-Newton has been in an orbit taking it through the trapped radiation belts and direct solar proton flux during the peak of the current solar cycle for over two and a half years. The MOS CCD detectors (E2V CCD22's) have degraded in charge transfer efficiency (CTE) as a result of damage created by high energy protons…

pnCCDs on XMM-Newton—42 months in orbit

Haberl, Frank; Freyberg, Michael; Dennerl, Konrad +11 more

XMM-Newton—a cornerstone mission of the European Space Agency's Horizon 2000 programme—was launched on December 10, 1999 into orbit. Since March 2000 more than 2000 scientific observations were made. An example will be shown. The X-ray pnCCD camera on EPIC is operating since then without severe problems. We will report about the system performance…
