ASTRO-E卫星上的X射线分光仪XRS是一个低温X射线探测器系统，利用在60 mK下工作的32像素微量热计阵列。在地面校准测量中，整个阵列获得了约12 eV（FWHM）的能量分辨率。我们采用了一种独特的三级低温系统，包括固体氖，液氦和绝热退磁制冷机，以获得长的低温寿命在轨道上。对氖贮箱的设计进行了优化，以获得约2年的氖寿命，这决定了整个低温系统的寿命。
The X-ray Spectrometer, XRS on board the ASTRO-E satellite is a cryogenic X-ray detector system utilizing a micro calorimeter array of 32 pixels operating at 60mK. An energy resolution of about 12eV (FWHM) has been obtained across the array in the ground calibration measurements. We adopted a unique three-stage cryogenic system consisting of solid neon, liquid helium, and an adiabatic de-magnetization refrigerator to obtain a long cryogenic lifetime in orbit. The design of the neon tank was optimized to obtain about 2 yr of the neon lifetime, which determines the lifetime of the whole cryogenic system.
