Low gain observations with EPIC pn-CCD on XMM-Newton Eckhard Kendziorra 01.12.00
three observations so far:
• rev.40 with thick filter, ?E ? 50 keV
• rev.90 with thin filter, ?E ? 25 keV
• rev.90 in closed position into radiation belts
low gain: gain of CAMEX is reduced by factor of 20
? spectral range for particles: 2 - 300 keV
