Millimeter-wave components were re-examined for high power (Mega-Watt) and steady-state (greater than one hour) operation. Some millimeter-wave components, including waveguide joints, vacuum pumping sections, power monitors, sliding waveguides, and injection windows, have been improved for high power CW (Continuous Waves) transmission. To improve transmission efficiency, information about the wave phase and mode content of high power millimeter-waves propagating in corrugated waveguides, which are difficult to measure directly, were obtained by a newly developed method based on retrieved phase information. To optimize the plasma heating efficiency, a proof-of-principle study of the injection polarization feedback control was performed in the low power test stand.

兆瓦毫米波处理技术优化聚变等离子体加热

重新检查了毫米波组件的高功率（兆瓦）和稳态（大于一小时）操作。一些毫米波组件，包括波导接头、真空泵部分、功率监视器、滑动波导和注入窗口，已经针对高功率 CW（连续波）传输进行了改进。为了提高传输效率，通过新开发的基于检索相位信息的方法获得了在波纹波导中传播的高功率毫米波的波相位和模式含量信息，这些信息难以直接测量。为了优化等离子体加热效率，在低功率试验台上进行了注入极化反馈控制的原理验证研究。
