Design and Power Tests of 500 MHz RF Cavity of CW Microtron for Industrial Applications

The 500 MHz RF cavity of a high intensity CW microtron for industrial applications was designed, and power tests of this cavity have been carried out. The cavity is composed of two cells with nose cones and coupling slots, having a total gap voltage of about 1 MV. The calculated Q-value was 37400 and the measured value was about 93% of the calculated one. An input power of 40 kW was successfully obtained in 65 h conditioning.
