Progress in X-ray CCD Peformance for the Astro-E2 X-ray Imaging Spectrometer
Abstract
We have developed X-ray CCD sensors for the Astro-E2 X-ray Imaging Spectrometer. Here we describe the performance benefits obtained from two innovations implemented in the CCD detectors developed for this instrument. First, we discuss the improved radiation tolerance afforded by a novel charge-injection structure. Second, we demonstrate for the first time the potential of a previously-developed chemisorption charging backside treatment process to produce back-illuminated X-ray sensors with excellent soft X-ray spectral resolution as well as improved quantum efficiency. We describe the changes in X-ray event detection algorithms required to obtain this improved performance.
