Abstract :
A harmonic peniotron has been designed for high efficiency and relative immunity to mode competition from gyrotron interactions. The device employs a 70 kV, 3.5 A, axis-encircling electron beam. To ensure stability from competing gyrotron interactions, the peniotron will operate in the lowest order mode of a slotted four-vane circuit, the /spl pi//2 mode. The 33 GHz, slotted second-harmonic peniotron is predicted to yield 125 kW with an electron efficiency of 58% and a device efficiency of 52%. The device is being constructed at UCD and will be driven by a recently developed Northrop Grumman Cusp electron gun.
