抽象。软X射线光谱仪(SXS)是第一个实现亚开尔文冷却系统操作冗余的天基仪器。它的冷却系统包括日本宇宙航空研究开发机构提供的一个超流氦低温恒温器和五个低温冷却器,以及美国航天局提供的三个带有四个主动热开关的绝热退磁制冷机。这些元件以两种方式之一来配置,以控制X射线微量热计探测器在50 mK下的散热器。“氦模式”是两种模式中较简单的一种,当液氦存在时使用,并使用所有五个低温冷却器和两个ADR。前两个ADR级一起工作,并将它们的热量直接排放到温度为1.1K的液体中。在“无冷冻剂模式”中,对于氦耗尽后的操作,第一级ADR操作不变,第二级被重新用于将空氦罐控制在1.5K,并且第三级将热量从1.5-K级传递到焦耳-汤姆逊冷却器的4.5-K界面。本文介绍了这种能力的开发和验证细节,并提供了对挑战,成功和教训的宝贵见解,这些经验教训可以使其他任务受益,特别是那些采用无冷冻剂或混合冷却系统的任务。
Abstract. The Soft X-ray Spectrometer (SXS) is the first space-based instrument to implement operational redundancy of a sub-Kelvin cooling system. Its cooling system includes a superfluid helium cryostat and five cryocoolers, provided by Japan Aerospace Exploration Agency, and three adiabatic demagnetization refrigerators (ADRs) with four active heat switches, provided by NASA. These elements are configured in one of two ways to control the heat sink of the x-ray microcalorimeter detectors at 50 mK. The “helium mode,” the simpler of the two modes, is used while liquid helium is present and uses all five cryocoolers and two ADRs. The first two ADR stages operate together and reject their heat directly to the liquid at ∼1.1  K. In the “cryogen-free mode,” for operation after the helium is depleted, the first stage ADR operation is unchanged, the second stage is repurposed to control the empty helium tank at ∼1.5  K, and the third stage transfers heat from the 1.5-K stage to the 4.5-K interface of the Joule–Thomson cooler. The development and verification details of this capability are presented within this paper and offer valuable insights into the challenges, successes, and lessons that can benefit other missions, particularly those employing cryogen-free or hybrid cooling systems.
