Abstract

A cusptron device operating at sixteenth cyclotron harmonic has been set up for the development of a compact and high power microwave source. An axis-encircling electron beam of 22Kev (=1.044) as the radiation source is produced from an annular thermionic cathode of 1.4 cm radius and 0.16 cm radial thickness with a pierce-type focusing electrode together with a cusp magnetic field. A 16-slotted waveguide with b/a=1.23 is used for the 2π mode operation where b and a are the radii of the slots and the inner wall of the waveguide respectively. a=1.7 cm is designed so that the operating magnetic field is 364 Gauss and the radiation frequency is 15.6GHz. 11% efficiency is achieved from particle simulation. The results of our experimental study will be presented and a comparison of the experimental results with those of particle simulation will be made.
