摘要

核光谱望远镜阵列(NuSTAR)是美国宇航局的一项小型探测任务,它将携带第一个聚焦硬x射线(5-80 keV)望远镜进入轨道。光学的地面校准提出了一个挑战,因为需要抑制全光学的有限源距离效应和感兴趣的能量范围是任何现有设施都无法满足的独特要求。本文介绍了NuSTAR光学地面校准的要求,以及雨水纪念校准设施(RaMCaF)的设计如何满足校准要求。近175米长的光束线运动48厘米直径5-100 keV x射线束,能够进行大直径光学元件的详细研究,如核星光学元件,以及平面多层涂层硅晶圆。

The Rainwater Memorial Calibration Facility for X-Ray Optics
The Nuclear Spectroscopic Telescope ARray (NuSTAR) is a NASA Small Explorer mission that will carry the first focusing hard X-ray (5–80 keV) telescope to orbit. The ground calibration of the optics posed a challenge as the need to suppress finite source distance effects over the full optic and the energy range of interest were unique requirements not met by any existing facility. In this paper we present the requirements for the NuSTAR optics ground calibration, and how the Rainwater Memorial Calibration Facility, RaMCaF, is designed to meet the calibration requirements. The nearly 175 m long beamline sports a 48 cm diameter 5–100 keV X-ray beam and is capable of carrying out detailed studies of large diameter optic elements, such as the NuSTAR optics, as well as flat multilayer-coated Silicon wafers.
