摘要
本文在Alcator C-Mod托卡马克上安装了一种新的空间分辨x射线晶体光谱仪(XCS)，该光谱仪能够测量类he和类h Ar Kalpha线的连续高分辨光谱(λ /dlambda > 6000)。该光谱仪改进了离子温度(Ti)的测量，具有优异的空间(~1 cm)和时间分辨率的本征旋转速度谱(vphi)，以及高电荷离子的原子物理特性。介绍了数据分析技术、(Ti)和(vphi)剖面结果、聚变中子产生的背景分析以及在国际托卡马克ITER和其他托卡马克上的性能预测。
Ion-temperature and rotation-velocity profile measurements from a spatially resolving x-ray crystal spectrometer on the alcator C-Mod tokamak
In this paper, a new spatially resolving X-ray crystal spectrometer (XCS) capable of measuring continuous spatial profiles of high resolution spectra (lambda/dlambda > 6000) of He-like and H-like Ar Kalpha lines has been installed on the Alcator C-Mod tokamak. The spectrometer has an improved measurements on ion temperature (Ti), intrinsic rotation-velocity profiles (vphi) with excellent spatial (~1 cm) and temporal resolution, and on the atomic physics of highly charged ions.The data analysis techniques, (Ti) and (vphi) profile results, analysis of background resulting from fusion neutrons, and predictions of performance on the international tokamak ITER and other tokamaks is presented.
