Abstract

A Ka-band gyrotron oscillator powered by a compact pulse- line accelerator has been operated using oscillator cavities with and without axial slots. The use of axial slots has been shown to suppress low starting current “whispering-gallery” modes, in particular, modes of the TEm2 type, allowing stable operation in a linearly polarized TE13 mode. A peak power of 35 MW has been observed at 6-percent efficiency.
