Real-Time Intensity and Profile Monitor of High Power CW Millimeter-Waves Propagating in a Corrugated Waveguide and Its Mode-Content Analysis

研制了大功率毫米波波束的实时位置和剖面监测系统。它可以安装在波纹波导的真空传输线上，用于核聚变装置的电子回旋共振加热系统。该监视器由连接在斜向弯曲反射器和散热器上的珀尔梯装置阵列组成。每个珀耳帖器件的输出电压反映反射器的温度。这些装置可以同时去除产生的热量。利用得到的温度信息，提出了传播模式分析的方法。

A real-time position and profile monitor of a high-power(MW level) millimeter-wave beam was developed. It can be installed in an evacuated transmission line with corrugated waveguides, which is used in the electron cyclotron resonance heating system for nuclear fusion devices. The monitor consists of a Peltier-device array attached on a miter-bend reflector and a heat sink. The output voltage of each Peltier device reflects the temperature of the reflector. The devices can remove generated heat at the same time. The method of a propagating mode analysis was also developed using the obtained temperature information.
