| Research Abstract |
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.
