NASA 的 X 射线光谱仪 (XRS) 微量热仪仪器自 2000 年 7 月起一直在劳伦斯利弗莫尔国家实验室的电子束离子阱 (EBIT) 设施中运行。该光谱仪目前正在进行第三次重大升级，以成为一种易于使用且性能极高的仪器，可用于广泛的 EBIT 实验。该光谱仪本身是宽带的，能够同时在 0.1 至 12 keV 范围内工作，并且通过操纵其工作条件，可以在高达 100 keV 的范围内工作。光谱分辨率与 XRS 的航天版本密切相关，从 2000 年 6 keV 时的 10 eV FWHM 开始，到 2003 年升级到 5.5 eV，并有望在 2007 年秋季达到约 3.8 eV。在此，我们回顾一下这种独特仪器的工作原理、过去六年中 EBIT 所进行的非凡科学研究以及未来升级的前景。具体来说，我们讨论了以高量子覆盖高能带（至少 100 keV）的升级...
NASA’s X-ray spectrometer (XRS) microcalorimeter instrument has been operating at the electron beam ion trap (EBIT) facility at Lawrence Livermore National Laboratory since July of 2000. The spectrometer is currently undergoing its third major upgrade to become an easy to use and extremely high-performance instrument for a broad range of EBIT experiments. The spectrometer itself is broadband, capable of simultaneously operating from 0.1 to 12 keV and has been operated at up to 100 keV by manipulating its operating conditions. The spectral resolution closely follows the spaceflight version of the XRS, beginning at 10 eV FWHM at 6 keV in 2000, upgraded to 5.5 eV in 2003, and will hopefully be ~3.8 eV in the fall of 2007. Here we review the operating principles of this unique instrument, the extraordinary science that has been performed at EBIT over the last six years, and prospects for future upgrades. Specifically, we discuss upgrades to cover the high-energy band (to at least 100 keV) with a high quantum ...
