Abstract

The cusptron device uses a cusp field to convert an axially moving beam into an axis-encircling electron beam (E-layer) as the radiation source. Such a beam configuration features the strongest finite-Larmor-radius effect for the harmonic interactions. This device uses a slotted cylinder waveguide, similar to the anode blocks of a magnetron, to determine the field pattern of the resonant mode. A sixteenth-harmonic cusptron oscillator has been designed and constructed. The device, which uses a 16-slot waveguide for the generation of the 16th cyclotron harmonic TE02 mode, works in the 2π mode. The beam energy and magnetic field of the device are 28.5 keV and 360 G, respectively. At present, only a small signal has been detected at the expected frequency of 15.8 GHz. Fine tuning of the operational parameters is underway in order to increase output to the expected level.
