Design and simulation for a 120-kW-average-power window test

A 120-kW-average-power window test facility is designed and simulated in order to investigate the influences of the factors, such as the dielectric loss, electromagnetic field intensity and multipactor on the output-power-capacity of windows. The configuration of the test system is present. The window box containing the test disk is particularly designed and optimized, which is operated at the cylindrical waveguide TE₁₁₁-mode, S-band. The simulation results shown that, when the cavity is in resonance, the window disk endures the strongest electric field intensity in the window box, and the equivalent power reaches its maximal on the upside surface of the disk, which satisfies the experiment requirement.
