| Abstract: | The design and operation of a 32 GHz pulsed gyrotron are reported. The device is step-tuned between the TE1,2 (24.16 GHz) and TE0,2 (31.78 GHz) modes with cathode voltages ranging from 30 to 40kV and beam current up to 5.0A. Experimental frequencies are in close agreement with the self-consistent calculated values and in the TE2,2 resonator mode an output peak power of 6kW corresponding to an 18% efficiency was measured by using a fast response calorimeter with a thermal sensitivity of 0.1°C/Wmin. |
