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

研制了一种高功率(MW级)毫米波波束位置和轮廓实时监测仪。它可以安装在带有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折式反射器和散热片上的Peltier器件阵列组成。每个Peltier器件的输出电压反映了反射器的温度。这些装置可以同时排出产生的热量。利用获得的温度信息，发展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.
