Paper Abstract

An experiment has been built to test the novel, efficient peniotron interaction at the third harmonic in a slotted eight-vane waveguide by using the axis-encircling electron beams produced by a gyroresonant rf accelerator. By configuring the oscillator so that the peniotron is excited as a forward wave at the cutoff frequency of a travelling-wave circuit, the peniotron can be made to dominate over the usually stronger gyrotron interaction. The 10 GHz peniotron will be driven by a 70 kV, 3.5 A axis-encircling electron beam with (alpha) equals v(perpendicular)/VZ equals 1.3 and is predicted by a nonlinear, self-consistent, multi-mode PIC code to yield 110 kW with 45% efficiency. The travelling-wave circuit is terminated on the upstream end by a load and by a transition to a TE41/TE11 mode converter on the collector end. PIC code simulation results and a description of the assembled experiment are presented.
