低地球轨道上的等离子体可能会损坏电子元件，并可能危及太空中的科学任务。在使命规划中，预测累积损伤和了解部件的辐射耐受性是非常重要的。在这篇手稿中，我们报告的单光子探测器和液晶偏振旋转器的辐射耐受性观察。我们的结论是，一个非制冷硅APD可以继续运作，从一个多月到超过卫星的寿命取决于轨道。液晶偏振旋转器也不受曝光剂量的影响。
Plasma in low earth orbit can damage electronic components and potentially jeopardize scientific missions in space. Predicting the accumulated damage and understanding components’ radiation tolerance are important in mission planning. In this manuscript, we report on the observed radiation tolerance of single photon detectors and a liquid crystal polarization rotator. We conclude that an uncooled Si APD could continue to operate from more than a month up to beyond the lifetime of the satellite depending on the orbit. The liquid crystal polarization rotator was also unaffected by the exposed dosage.
