Abstract

In the KSTAR Tokamak, a "Tangential Thomson Scattering" (TTS) diagnostic system has been designed and installed to measure electron density and temperature profiles. In the edge system, TTS has 12 optical fiber bundles to measure the edge profiles with 10-15 mm spatial resolution. These 12 optical fibers and their spatial resolution are not enough to measure the pedestal width with a high accuracy but allow observations of L-H transition or H-L transitions at the edge. For these measurements, the prototype ITER edge Thomson Nd:YAG laser system manufactured by JAEA in Japan is installed. In this paper, the KSTAR TTS system is briefly described and some TTS edge profiles are presented and compared against the KSTAR Charge Exchange Spectroscopy and other diagnostics. The future upgrade plan of the system is also discussed in this paper.

摘要

在韩国超导托卡马克先进研究装置（KSTAR）中，已设计并安装了一个“切向汤姆逊散射”（TTS）诊断系统，用于测量电子密度和温度分布。在边缘系统中，TTS有12束光纤，以10 - 15毫米的空间分辨率测量边缘分布。这12根光纤及其空间分辨率不足以高精度测量台基宽度，但可用于观测边缘的低约束（L）到高约束（H）转变或H - L转变。为进行这些测量，安装了由日本原子能机构（JAEA）制造的国际热核聚变实验堆（ITER）边缘汤姆逊钕钇铝石榴石激光系统原型。本文简要介绍了KSTAR的TTS系统，并给出了一些TTS边缘分布，并与KSTAR电荷交换光谱法及其他诊断方法进行了比较。本文还讨论了该系统未来的升级计划。
