Design of a gridded cusp gun for a W-band gyro-TWA

Research output: Contribution to conferencePaper

Abstract

This paper reports the design and optimization of a gridded cusp electron gun for a W-band gyrotron traveling wave amplifier. By applying positive or negative biasing potentials to additional electrodes that are placed in front of the emitter, the electron beam can be switched on and off quickly and easily. In simulations, an optimal velocity ratio (alpha) of 1.12 with an alpha spread of ~10.7% was achieved when the gridded-type gun was operated at a beam voltage of 40 kV and a current of 1.7 A.
