Abstract

The design and operation of a high power pulsed gyrotron are reported. The device runs in pulsed regime with a 25 μs pulse length at a frequency repetition rate of 10 Hz and during operation the pressure in the tube is ordinarily less than 4.0×10^-7 Torr. Several TE modes were detected over the magnetic field range 9.5 to 12.5 kG and the measured resonant frequencies (29.0 to 32.0 GHz) showed to be in close agreement with the self-consistent calculated values. Experiments are currently under way to measure the absolute ouput power and to identify the modes through field pattern measurement techniques
