Astro-E2 X 射线天文台高分辨率 X 射线光谱仪焦平面上的方形 32 像素微量热计阵列是新一代硅基微量热计中的第一个。该阵列比其前身（在 Astro-E 上推出的双线性阵列）具有许多优势。其最重要的优点是：(1) 在 6keV（现在为 6eV FWHM）下，能量分辨率提高了两倍，(2) 热时间常数加快了两倍，(3) 每个像素都具有高斯线响应。我们将讨论带来这些和其他优点的设计变更。
The square-format 32-pixel microcalorimeter array at the focal plane of the high-resolution X-ray spectrometer on the Astro-E2 X-ray Observatory is the first of a new generation of silicon-based microcalorimeters. This array has numerous advantages over its predecessor, the bilinear array that was launched on Astro-E. Foremost among its benefits are: (1) the energy resolution is improved by a factor of two at 6keV (now 6eV FWHM), (2) the thermal time constant is a factor of two faster, and (3) each pixel has a Gaussian line response. We will discuss the design changes that have led to these and other advantages.
