摘要:

在为期三年的评估阶段的LOFT任务,候选人的M3发射机会的欧空局宇宙视野计划,我们估计和测量的硅漂移探测器(SDD)的卫星仪器的辐射损伤。特别是,我们用质子(能量为0.8和11兆电子伏)照射探测器,以研究漏电流的增加和位移损坏产生的电荷收集效率的变化,我们用超高速尘埃颗粒“轰击”探测器,以测量碎片撞击的影响。在本文中,我们描述的测量和讨论的LOFT任务的背景下的结果。

英文摘要:

During the three years long assessment phase of the LOFT mission, candidate to the M3 launch opportunity of the ESA Cosmic Vision programme, we estimated and measured the radiation damage of the silicon drift detectors (SDDs) of the satellite instrumentation. In particular, we irradiated the detectors with protons (of 0.8 and 11 MeV energy) to study the increment of leakage current and the variation of the charge collection efficiency produced by the displacement damage, and we "bombarded" the detectors with hypervelocity dust grains to measure the effect of the debris impacts. In this paper we describe the measurements and discuss the results in the context of the LOFT mission.
