由NASA/Goddard太空飞行中心(GSFC)建造的32像素实验室微量热计光谱仪现在是劳伦斯·利弗莫尔国家实验室电子束离子陷阱和辐射特性小组常规使用的光谱分析套件的组成部分。名为XRS/EBIT的第二代实验室仪器与铃鹿X射线天文台(前身为Astro-E2)上的XRS仪器几乎相同。探测器阵列来自相同的处理晶片，并且使用相同的HgTe吸收体。它被用来测量各种辐射源的光子发射。这包括来自实验室模拟天体源的X射线发射，来自高电荷态Au离子的X射线发射，以及电荷交换和辐射电子俘获后的X射线发射。广泛的应用证明了高分辨率、高效率的低温探测器的多功能性，它能够在最少的操作员服务下连续收集数据。
The 32 pixel laboratory microcalorimeter spectrometer built by the NASA/Goddard Space Flight Center (GSFC) is now an integral part of the spectroscopy suite used routinely by the electron beam ion trap and radiative properties group at the Lawrence Livermore National Laboratory. The second generation laboratory instrument, dubbed the XRS/EBIT, is nearly identical to the XRS instrument on the Suzaku X-ray Observatory, formerly Astro-E2. The detector array is from the same processed wafer and uses the same HgTe absorbers. It is being used to measure the photon emission from a variety of radiation sources. These include X-ray emission from laboratory simulated celestial sources, X-ray emission from highly charged ions of Au, and X-ray emission following charge exchange and radiative electron capture. The wide range of applications demonstrates the versatility of a high-resolution, high-efficiency low-temperature detector that is able to collect data continually with minimal operator servicing.
