用软质子和超高速尘埃粒子进行的加速器实验:应用于未来X射线飞行任务的正在进行的项目
Accelerator experiments with soft protons and hyper-velocity dust particles: application to ongoing projects of future X-ray missions
摘要:
我们报告了我们目前正在进行的活动,目的是用软质子和超高速尘埃粒子进行加速器实验。其中包括测试不同类型的X射线探测器和相关部件(如滤光片),以及测量软质子和超高速尘埃粒子从X射线镜壳上散射的情况。这些活动已被确定为一些正在进行的空间项目的一个目标,目的是评估环境辐射和尘埃造成的风险,并就可能的损坏或性能退化对所采用的仪器进行鉴定。在本文中,我们专注于测试的硅漂移探测器(SDDs)上使用的LOFT空间任务。我们使用蒂宾根大学和海德堡马克斯普朗克核物理研究所(MPIK)的范德格拉夫加速器,分别进行软质子和超高速尘埃测试。我们提出的实验装置通过进行测试,活动的状态和目前取得的一些非常初步的结果。
英文摘要:
We report on our activities, currently in progress, aimed at performing accelerator experiments with soft protons and hyper-velocity dust particles. They include tests of different types of X-ray detectors and related components (such as filters) and measurements of scattering of soft protons and hyper-velocity dust particles off X-ray mirror shells. These activities have been identified as a goal in the context of a number of ongoing space projects in order to assess the risk posed by environmental radiation and dust and qualify the adopted instrumentation with respect to possible damage or performance degradation. In this paper we focus on tests for the Silicon Drift Detectors (SDDs) used aboard the LOFT space mission. We use the Van de Graaff accelerators at the University of Tübingen and at the Max Planck Institute for Nuclear Physics (MPIK) in Heidelberg, for soft proton and hyper-velocity dust tests respectively. We present the experimental set-up adopted to perform the tests, status of the activities and some very preliminary results achieved at present time.
