Paper Abstract

For electron cyclotron heating to be economically attractive for large scale tokamaks, such as ITER, the unit power source,the gyrotron, should be above 1 MW cw. At frequencies of interest, —140 GHz, mode competition makes the realization ofsuch high power devices quite difficult. Reduction of the number of modes that compete by use of a coaxial insert in thecavity has been found to be effective. We report here on the design of a 3 MW, 140 GHz gyrotron based on the TE23,16mode, including brief discussions of the cavity, electron gun and output mode converter.
