摘要：

The X-ray Spectrometer (XRS-2) instrument on the Japanese Space Agency (JAXA) Astro-E2 spacecraft will measure faint X-ray emissions in the energy range of 0.2-10 keV. A square array of 32 X-ray microcalorimeters used will be able to distinguish individual photons to better than 10 eV at 6 keV, with a quantum efficiency near 100%. The detectors are cooled to 60 mK by means of an adiabatic demagnetization refrigerator (ADR). The ADR rejects heat to a 1.3 K superfluid helium tank, which is surrounded by a 17 K solid neon tank. A Stirling cycle cryocooler precools an outer shield around the neon tank. This system will provide an estimated 3 years of on-orbit lifetime. This paper describes the helium insert, the ADR, the high temperature superconducting leads, and early on-orbit performance. Published by Elsevier B.V.
