摘要

使用反射光栅的高分辨率、高通量软X射线光谱有可能解开关于高能宇宙的许多问题的答案。为了使特派团能够在未来使用这项技术,需要证明精确对准反射光栅的能力。水回收X射线火箭(WRXR)是一种软X射线光谱仪,于2018年4月从夸贾林环礁成功发射,需要共对准的X射线反射光栅。WRXR的设计目的是在大视场内产生船帆座超新星遗迹的中等分辨率光谱。光栅模块制造完成,集成到火箭有效载荷上,通过了环境测试,并成功发射和回收。本文描述了WRXR的光栅和反射镜对准方法,以及它们固有的系统不确定性。还讨论了满足未来X射线光谱仪更严格的对准公差所需的对准方法的改进。

Grating Alignment for the Water Recovery X-Ray Rocket (WRXR)
High-resolution, high-throughput soft X-ray spectroscopy using reflection gratings has the potential to unlock answers to many of the questions about the high-energy Universe. To enable missions to use this technology in the future, the ability to precisely align reflection gratings needs to be demonstrated. The Water Recovery X-ray Rocket (WRXR), a soft X-ray spectrometer that successfully launched in April 2018 from the Kwajalein Atoll, required co-aligned X-ray reflection gratings. WRXR was designed to produce a moderate-resolution spectrum of the Vela supernova remnant over a large field-of-view. The grating module was manufactured, integrated onto the rocket payload, passed environmental testing and was successfully launched and recovered. This paper describes the grating and mirror alignment methodologies for WRXR, and their inherent systematic uncertainties. Improvements to the alignment method that are required to meet the tighter alignment tolerances of future X-ray spectrometers are also discussed.

期刊介绍: The Journal of Astronomical Instrumentation (JAI) publishes papers describing instruments and components being proposed, developed, under construction and in use. JAI also publishes papers that describe facility operations, lessons learned in design, construction, and operation, algorithms and their implementations, and techniques, including calibration, that are fundamental elements of instrumentation. The journal focuses on astronomical instrumentation topics in all wavebands (Radio to Gamma-Ray) and includes the disciplines of Heliophysics, Space Weather, Lunar and Planetary Science, Exoplanet Exploration, and Astroparticle Observation (cosmic rays, cosmic neutrinos, etc.). Concepts, designs, components, algorithms, integrated systems, operations, data archiving techniques and lessons learned applicable but not limited to the following platforms are pertinent to this journal. Example topics are listed below each platform, and it is recognized that many of these topics are relevant to multiple platforms. Relevant platforms include: Ground-based observatories[...] Stratospheric aircraft[...] Balloons and suborbital rockets[...] Space-based observatories and systems[...] Landers and rovers, and other planetary-based instrument concepts[...]
