Abstract : A Ka-band gyrotron oscillator powered by a compact pulseline 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 TE(m2) type, allowing stable operation in a linearly-polarized TE(13) mode. A peak power of 35 MW has been observed at 6% efficiency. Keywords: Gyrotron oscillator, Low start oscillation threshold currents, Cylindrical cavity, Slotted, Unslotted cavities.
