Astro-H(Hitomi)轨道X射线天文台上的软X射线光谱仪(SXS)配备了一个由36个硅热敏电阻X射线量热计组成的阵列,该阵列经过优化,可在0.3-12 keV波段对天体物理源进行高光谱分辨率X射线成像光谱分析。广泛的飞行前校准测量是我们对每个像素和事件等级的脉冲高度能量关系和能量分辨率、望远镜收集面积、探测器效率和脉冲到达时间进行建模的基础。 由于使命操作的提前终止,我们需要从仅在使命开始的几天内进行的观测中提取最大信息,此时机载校准源尚未调试,杜瓦瓶仍处于热平衡状态,因此我们用于重建每像素时间相关脉冲-高度-能量关系的技术必须进行修改。使用的绝对能量标度校准在一个单一的时间使用的基准从板载放射源,和校准的一个主要的时间依赖性增益漂移组件使用一个专用的校准像素,以及剩余的时间依赖性变化使用光谱从英仙座星系团的组合重建的增益标度。还使用机载放射源测量了能量分辨率。这与仪器一级的测量结果是一致的,说明由于航天器系统的干扰,噪声略有增加。我们使用两个望远镜的观测来验证我们的望远镜面积和探测器效率的模型,并推导出一个更准确的值的闸阀Be窗口的厚度,这还没有被打开的时间使命操作停止。我们使用的蟹状星云脉冲星的观测,以改善像素到像素的定时和验证的绝对定时。
The Soft X-ray Spectrometer (SXS) onboard the Astro-H (Hitomi) orbiting x-ray observatory featured an array of 36 silicon thermistor x-ray calorimeters optimized to perform high spectral resolution x-ray imaging spectroscopy of astrophysical sources in the 0.3-12 keV band. Extensive pre- flight calibration measurements are the basis for our modeling of the pulse-height-energy relation and energy resolution for each pixel and event grade, telescope collecting area, detector efficiency, and pulse arrival time. Because of the early termination of mission operations, we needed to extract the maximum information from observations performed only days into the mission when the onboard calibration sources had not yet been commissioned and the dewar was still coming into thermal equilibrium, so our technique for reconstructing the per-pixel time-dependent pulse-height-energy relation had to be modified. The gain scale was reconstructed using a combination of an absolute energy scale calibration at a single time using a fiducial from an onboard radioactive source, and calibration of a dominant time-dependent gain drift component using a dedicated calibration pixel, as well as a residual time-dependent variation using spectra from the Perseus cluster of galaxies. The energy resolution was also measured using the onboard radioactive sources. It is consistent with instrument-level measurements accounting for the modest increase in noise due to spacecraft systems interference. We use observations of two pulsars to validate our models of the telescope area and detector efficiency, and to derive a more accurate value for the thickness of the gate valve Be window, which had not been opened by the time mission operations ceased. We use observations of the Crab pulsar to refine the pixel-to-pixel timing and validate the absolute timing.
