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.

研制了一种高功率毫米波束流位置和轮廓实时监测仪。它可以安装在真空波纹波导传输线中，用于核聚变装置的电子回旋共振加热系统。该监测器由一个珀尔帖装置阵列连接在一个斜弯反射器和散热器。每个珀耳帖器件的输出电压反映反射器的温度。这些设备可以同时去除产生的热量。传播模式分析的方法也开发了使用所获得的温度信息。
