Abstract

The ITER low field side reflectometer faces some unique design challenges, among which are included the effect of relativistic electron temperatures and refraction of probing waves. This paper utilizes GENRAY, a 3D ray tracing code, to investigate these effects. Using a simulated ITER operating scenario, characteristics of the reflected millimeter waves after return to the launch plane are quantified as a function of a range of design parameters, including antenna height, antenna diameter, and antenna radial position. Results for edge/SOL measurement with both O- and X-mode polarizations using proposed antennas are reported.

摘要

国际热核聚变实验堆（ITER）低场侧反射计面临一些独特的设计挑战，其中包括相对论电子温度的影响和探测波的折射。本文利用三维射线追踪程序GENRAY来研究这些影响。使用模拟的ITER运行场景，将返回发射平面后的反射毫米波特性量化为一系列设计参数的函数，这些参数包括天线高度、天线直径和天线径向位置。报告了使用所提出的天线进行O模和X模极化的边缘/刮削层测量结果。
