Design of a 24 GHz, 30 kW technology gyrotron operating at the second harmonic

One of the major obstacles to the use of high frequency (> 10 GHz) microwaves for technological applications is the fact that suitable, inexpensive, easy-to-use sources are not readily available. In this study, we consider the possibility of a moderate power (25-50 kW) gyrotron operating at the ISM (industrial, scientific, medical) frequency of 24.1 GHz. Particular attention is paid to the use of readily available components. Operation at the second harmonic is considered so that one can obtain radiation at the given frequency with only half the magnetic field required.
