The effect of RF-space charge fields on the beam-field interaction in gyrotrons is reviewed. This effect, formerly considered unimportant, is found to cause recognisable differences in simulations of gyrotrons with high current density, such as today

The RF behavior of a 42-GHz 200-kW continuous-wave (CW) gyrotron for plasma heating in a small experimental tokamak is presented in this paper. The operating mode, as a matter of technical convenience, is the mode, as is required by the end user. Des

A design concept of a 250 GHz, ≈ 50 W, CW, second harmonic gyrotron for spectroscopy will be presented in this paper. Mode competition, in particular with regard to competition with first harmonic modes, and mode selection procedures are carefully

The modulation of the output power of a 140 GHz gyrotron for fusion plasma heating at the W7-X Stellarator is simulated numerically. It is shown that for appropriate beam properties, power modulation is possible. The output power shows almost no depe

We investigate the possibility of multifrequency operation of a 140-GHz gyrotron, which is designed to operate in the TE/sub 22,8/ mode at 140 GHz and the TE/sub 19,6/ mode at 111 GHz or the TE/sub 17,6/ mode at 105 GHz, for which existing equipment
