The Full-sun Ultraviolet Rocket SpecTrograph (FURST) is a sounding rocket designed to acquire the first full-disk integrated high resolution vacuum ultraviolet (VUV) spectra of the Sun. The data enable analysis of the Sun comparable to stellar spectra measured by astronomical instruments such as those on board the Hubble Space Telescope. The mission is jointly operated by teams at Montana State University (MSU), developing the instrument, and Marshall Space Flight Center (MSFC), developing the camera and calibration systems, and is scheduled to launch from White Sands Missile Range, New Mexico, in 2022. This mission requires the development of a pre- and post-launch calibration plan for absolute radiometric and wavelength calibration to reliably generate Hubble analogue spectra. Absolute radiometric calibration, though initially planned to be performed at the National Institute for Standards and Technology (NIST) calibration facilities, is now planned to be completed with a portable VUV calibration system provided by MSFC, due to instrument incompatibilities with NIST infrastructure. The portable calibration system is developed to provide absolute wavelength calibration and track changes in calibration over the duration of the mission. The portable calibration system is composed mainly of a VUV collimator equipped with an extreme ultraviolet line source and calibrated photodiodes. The calibration system is developed to accommodate both repeatable wavelength and radiometric testing of the FURST instrument at various test sites before and after launch. Presented here are the requirements, design, and implementation of this portable calibration system with a focus on those features most significant to radiometric measurements.

全太阳紫外火箭光谱仪便携式校准系统设计

全太阳紫外线火箭光谱仪 (FURST) 是一种探空火箭，旨在获取太阳的第一个全盘集成高分辨率真空紫外线 (VUV) 光谱。这些数据使对太阳的分析与由哈勃太空望远镜等天文仪器测量的恒星光谱相媲美。该任务由开发仪器的蒙大拿州立大学 (MSU) 和开发相机和校准系统的马歇尔太空飞行中心 (MSFC) 的团队共同执行，并计划从新墨西哥州的白沙导弹靶场发射升空。 2022. 这项任务需要为绝对辐射测量和波长校准制定发射前和发射后校准计划，以可靠地生成哈勃模拟光谱。绝对辐射校准，尽管最初计划在美国国家标准与技术研究院 (NIST) 的校准设施中进行，但由于仪器与 NIST 基础设施不兼容，现在计划使用 MSFC 提供的便携式 VUV 校准系统来完成。便携式校准系统旨在提供绝对波长校准并跟踪任务期间校准的变化。便携式校准系统主要由配备极紫外线光源和校准光电二极管的真空紫外准直器组成。开发校准系统是为了适应 F​​URST 仪器在发射前后在不同测试地点的可重复波长和辐射测试。这里介绍的是要求、设计、
