Abstract

Stability of the intermediate frequency (IF) in the far-infrared polarimeter-interferometer diagnostic system is critically important for the long pulse discharge experiments on the EAST tokamak. In this note, a real-time remote/local IF stability control system is described. The measured plasma parameters, including the Faraday rotation angle, electron density, lower hybrid wave, and plasma current, are obtained with the aid of this newly developed IF stability control system.

摘要

在超导托卡马克核聚变实验装置（EAST）上进行长脉冲放电实验时，远红外偏振干涉仪诊断系统中中频（IF）的稳定性至关重要。在本说明中，描述了一种实时远程/本地中频稳定性控制系统。借助这个新开发的中频稳定性控制系统，可以获得包括法拉第旋转角、电子密度、低杂波和等离子体电流在内的实测等离子体参数。
