Abstract

Radial profiles of electron temperature and density are measured at high spatial (∼1 mm) and temporal (≥10 μs) resolution using a thermal supersonic helium jet. A highly accurate detection system is applied to well-developed collisional-radiative model codes to produce the profiles. Agreement between this measurement and an edge Thomson scattering measurement is found to be within the error bars (≲20%). The diagnostic is being used to give profiles near the ion cyclotron resonant heating antenna on TEXTOR to better understand RF coupling to the core.

摘要

利用热超声氦射流，以高空间分辨率（约1毫米）和高时间分辨率（≥10微秒）测量了电子温度和密度的径向分布。将一个高精度检测系统应用于完善的碰撞辐射模型代码，以生成这些分布。结果发现，该测量值与边缘汤姆逊散射测量值之间的一致性在误差范围内（≲20%）。这种诊断方法正用于获取TEXTOR上离子回旋共振加热天线附近的分布，以便更好地理解射频与堆芯的耦合情况。
