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.
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。
