摘要:

硅成像探测器的稳定性和测光精度对于宜居世界天文台以及一系列NASA任务至关重要,这些任务将探索时域天体物理学和天文学,光谱范围涵盖软X射线至紫外、可见光和近红外。探测器稳定性是NASA任务中最古老且最具挑战性的问题之一。在极紫外波段,挑战尤为严峻,因为高能光子的近表面吸收会导致表面快速退化。本文分析了辐射引起的表面电荷变化对探测器稳定性和测光精度的影响,以评估对未来NASA任务的影响。

英文摘要:

Stability and photometric accuracy of silicon imaging detectors are essential for the Habitable Worlds Observatory and a range of NASA missions that will explore time domain astrophysics and astronomy over a spectral range spanning soft X-rays through the ultraviolet, visible, and near infrared. Detector stability is one of the oldest and most challenging problems in NASA missions. The challenges are particularly acute in the extreme ultraviolet range, where near-surface absorption of high-energy photons causes surfaces to degrade rapidly. In this paper, the effects of radiation-induced variability of surface charge on detector stability and photometric accuracy are analyzed in order to assess the implications for future NASA missions.
