Caliste-SO 是一款 CdTe 混合探测器，设计用作硬 X 射线傅里叶望远镜的光谱仪。该成像技术分别于 1991 年和 2002 年在 Yohkoh 卫星和 RHESSI 卫星上实施，以实现具有光谱功能的太阳耀斑角秒角分辨率图像。下一代此类仪器将是欧洲航天局于 2011 年采用的太阳轨道飞行器任务上的光谱仪望远镜成像 X 射线 (STD())，并于 2017 年发射。Caliste-SO 的设计和性能可实现 4 至 150 keV 的高光谱分辨率和高计数率测量，对质量、功率和体积等航天器资源的需求有限（对于行星际任务至关重要）。该论文报告了STIX 的 Caliste-SO 设备，描述了在瑞士和法国建立的测试设施。它说明了将安装在 STD 工程模型中的第一批生产样品所获得的一些结果。(C) 2014 Elsevier B.V. 保留所有权利。
Caliste-SO is a CdTe hybrid detector designed to be used as a spectrometer for a hard X-ray Fourier telescope. The imaging technique was implemented in the Yohkoh satellite in 1991 and the RHESSI satellite in 2002 to achieve arc-second angular resolution images of solar flares with spectroscopic capabilities. The next generation of such instruments will be the Spectrometer Telescope Imaging X-rays (STD() on-board the Solar Orbiter mission adopted by the European Space Agency in 2011 for launch in 2017. The design and performance of Caliste-SO allows both high spectral resolution and high count rate measurements from 4 to 150 keV with limited demands on spacecraft resources such as mass, power and volume (critical for interplanetary missions). The paper reports on the flight production of the Caliste-SO devices for STIX, describing the test facilities built-up in Switzerland and France. It illustrates some results obtained with the first production samples that will be mounted in the STD( engineering model. (C) 2014 Elsevier B.V. All rights reserved.
