摘要

美国国家航空航天局是詹姆斯·韦伯太空望远镜（JWST）的任务负责人，该望远镜是计划于2021年发射的下一个“大天文台”。美国国家航空航天局直接负责集成和测试（I&T）计划，该计划最终在美国国家航空宇航局约翰逊航天中心的A舱对飞行望远镜和仪器模块进行了端到端的低温真空光学测试。历史悠久的A舱是约翰逊航天中心最大的热真空舱，也是世界上最大的太空模拟舱之一。A室经过了重大的现代化改造，以支持JWST测试的深冷、真空和清洁度要求。本文介绍了A室设施的升级：隔热罩、氦气制冷、液氮系统、高真空系统、清洁气流系统和公用设施。

Modernization of NASA Johnson Space Center’s Chamber A to support Cryogenic Vacuum Optical Testing of the James Webb Space Telescope (JWST)

NASA is the mission lead for the James Webb Space Telescope (JWST), the next of the “Great Observatories,” scheduled for launch in 2021. NASA is directly responsible for the integration and test (I&T) program that culminated in an end-to-end cryo vacuum optical test of the flight telescope and instrument module in Chamber A at NASA Johnson Space Center. Historic Chamber A is the largest thermal vacuum chamber at Johnson Space Center and one of the largest space simulation chambers in the world. Chamber A has undergone a major modernization effort to support the deep cryogenic, vacuum and cleanliness requirements for testing the JWST. This paper describes the upgrades to the Chamber A facility: Thermal Shrouds, Helium Refrigeration, Liquid Nitrogen System, High Vacuum System, Clean Airflow System, and Utilities.
