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//m//2 type, allowing stable operation in a linearly polarized TE//1//3 mode. A peak power of 35 MW has been observed at 6% efficiency.
