X射线微量热计阵列非常适合于解决高能天体物理中的关键问题。日本/美国的Astro-E2任务将部署一个分辨率为6 eV的32像素微热量计阵列。这项任务计划于2005年发射。除了Astro-E2,NASA正在制定星座-X任务,以提供急剧增加的收集面积,四个独立的航天器,每个都有大面积光学元件和1k像素热量计阵列,提供2-4 eV的能量分辨率。我们将描述这些任务中的微热量计仪器,并提到它们的一些科学目标。
X-ray microcalorimeter arrays are well suited to address key problems in high-energy astrophysics. The Japan/US Astro-E2 mission will deploy a 32-pixel array of microcalorimeters with 6eV resolution. This mission is scheduled for launch in 2005. Beyond Astro-E2, NASA is formulating the Constellation-X mission to provide a dramatic increase in collecting area with four separate spacecraft each with large area optics and 1k-pixel calorimeter arrays providing an energy resolution of 2–4eV.We will describe the microcalorimeter instrumentation on these missions and mention some of their scientific objectives.
