A high-resolution x-ray imaging crystal spectrometer, whose concept was tested on NSTX and Alcator C-Mod, is being designed for the large helical device (LHD). This instrument will record spatially resolved spectra of helium-like Ar(16+) and will provide ion temperature profiles with spatial and temporal resolutions of <2 cm and ≥10 ms, respectively. The spectrometer layout and instrumental features are largely determined by the magnetic field structure of LHD. The stellarator equilibrium reconstruction codes, STELLOPT and PIES, will be used for the tomographic inversion of the spectral data.
一种高分辨率X射线成像晶体光谱仪正在为大型螺旋装置（LHD）进行设计，其概念已在国家球形环实验装置（NSTX）和阿尔卡特C-Mod装置上进行了测试。该仪器将记录类氦氩离子（Ar16 +）的空间分辨光谱，并将分别提供空间和时间分辨率小于2厘米和大于等于10毫秒的离子温度剖面。光谱仪的布局和仪器特性在很大程度上由LHD的磁场结构决定。恒星器平衡重建代码STELLOPT和PIES将用于光谱数据的断层反演。
