摘要

摘要介绍了用于测量线性积分电子密度的 T-15MD 托卡马克微波干涉仪的显著特点，以及处理和记录其信号的系统。分析了微波干涉仪信号的相位稳定性。介绍了在 T-15MD 托卡马克首次实验活动中使用微波干涉仪进行测量的结果。通过使用模拟相位计和对数字化微波干涉仪信号（中频信号和本地振荡器信号）进行后处理，提取了相位值。结果表明，用这两种方法计算等离子体密度的结果是一致的。

T-15MD Tokamak Microwave Interferometer for Measuring the Average Electron Density of Plasma

The distinctive features of the T-15MD tokamak microwave interferometer for measuring linearly integrated electron density, as well as the system for processing and recording its signals, are presented. The phase stability of microwave interferometer signals is analyzed. The results of measurements with a microwave interferometer during the first experimental campaign of the T-15MD tokamak are presented. The phase values were extracted by using an analog phase meter and post-processing of digitized microwave interferometer signals: an intermediate frequency signal and a local oscillator signal. It is shown that the results of the plasma density calculation by these two methods coincide.
