我们为Astro-E2 X射线成像光谱仪研制了X射线CCD传感器。在这里,我们描述的性能优势,从两个创新的CCD探测器开发的仪器。首先,我们讨论了一种新的电荷注入结构所提供的改进的耐辐射性。其次,我们首次展示了先前开发的化学吸附充电背面处理工艺的潜力,以生产具有优异的软X射线光谱分辨率和提高的量子效率的背照式X射线传感器。我们描述了X射线事件探测算法的变化,以获得这种改进的性能,并简要比较XIS传感器的性能,目前在轨道上运行的背照式探测器。
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, and briefly compare the performance of XIS sensors to that of back-illuminated detectors currently operating on-orbit.
