本文介绍了传统的汤姆逊散射诊断已开发的托卡马克ISTTOK等离子体的电子温度和等离子体密度的多点测量。该设计是基于一个单一的激光脉冲，两个多输入三通道光谱仪，一个数字示波器，和一个时间延迟技术。特殊的收集光学系统，优化的探测器，和高传输单纤维与大数值孔径已被用来提高灵敏度和空间分辨率。测量点的数量可以通过增加光纤的数量来扩展，而无需改变收集光学器件或光中继系统。结果与其他诊断方法测定的结果一致。
This article describes the conventional Thomson scattering diagnostic that has been developed for multipoint measurements of the electron temperature and plasma density of the tokamak ISTTOK plasma. The design is based on a single laser pulse, two multi-input three channel spectrometers, one digital oscilloscope, and a time-delay technique. Special collection optics, optimized detectors, and high transmission monofibers with large numerical aperture have been used to increase the sensitivity and spatial resolution. The number of measurement points can be extended by increasing the number of fibers without altering the collection optics or light relay system. Results are in good agreement with those determined with other diagnostics.
