The Charge Exchange Recombination Spectroscopy (CXRS) diagnostic has become a routine diagnostic on almost all major high temperature fusion experimental devices. For the optimized stellarator Wendelstein 7-X (W7-X), a highly flexible and extensive CXRS diagnostic has been built to provide high-resolution local measurements of several important plasma parameters using the recently commissioned neutral beam heating. This paper outlines the design specifics of the W7-X CXRS system and gives examples of the initial results obtained, including typical ion temperature profiles for several common heating scenarios, toroidal flow and radial electric field derived from velocity measurements, beam attenuation via beam emission spectra, and normalized impurity density profiles under some typical plasma conditions.

Wendelstein 7-X 的电荷交换复合光谱
电荷交换重组光谱 (CXRS) 诊断已成为几乎所有主要高温聚变实验设备的常规诊断。对于优化的仿星器 Wendelstein 7-X (W7-X)，构建了高度灵活和广泛的 CXRS 诊断，以使用最近委托的中性束加热提供几个重要等离子体参数的高分辨率局部测量。本文概述了 W7-X CXRS 系统的设计细节，并给出了获得的初始结果的示例，包括几种常见加热场景的典型离子温度分布、来自速度测量的环形流和径向电场、通过束发射光谱的束衰减，以及一些典型等离子体条件下的归一化杂质密度分布。
