Abstract

We report on the operating characteristics of a 32 GHz pulsed gyrotron that has been designed and built at the Associate Plasma Laboratory of INPE. Experimental results include frequency and power measurements on resonant modes TE_5.1, TE_2.2 and TE _0.2. Measured frequencies are in close agreement with the self-consistent calculated values and power measurements were made using a fast response calorimeter with a sensitivity of 0.1°C/Wmin. Results are presented for beam voltages from 30 to 40 kV and electron beam current up to 5.0 A. In single TE_2.2-mode operation at 30.38 GHz an output peak power of 6 kW was obtained with an overall efficiency of 18%
