Abstract

Along with high power and high efficiency operation around 240 GHz, the requirements of DEMO gyrotrons include the possibility of multi-frequency operation and fast frequency tunability in 2-3 GHz steps. In this paper, multi-frequency operation of a proposed design for a conventional cavity DEMO gyrotron is presented, including operating parameters at different frequencies. The performance of the gyrotron is simulated considering realistic electron beam parameters.
