Abstract
Next-generation X-ray imaging missions require fast, low-noise detectors that can survive the harsh environment of space without significant loss of performance. As part of a detector development effort toward a mission such as Lynx, we report on the effects of proton exposure on the spectral performance, dark current and charge transfer efficiency of a back illuminated MIT Lincoln Laboratory CCID93. The CCD has 8 micron pixels and can be clocked with 2.5MHz pixel speeds with CMOS compatible voltage swings. The 40 MeV proton dose is chosen to represent typical on orbit exposure. Variations with charge injection, temperature, and clocking speed are explored. These results are compared with those of the front illuminated version of the same device.
