Paper Abstract

To maximize the output power of 35-GHz gyrotron with operating TE mode, 021 the length of its cavity was varied. Optimal cavity length corresponding to the peak power of about 300 kW has been found experimentally . In gyro Iron W ith longer cavity output power decreases down to 190 kW due to overbunching of electrons while in gyrotron with shorter cavity power restriction at the I evel of 2 1.0 kW is caused by the self-exitation of spurious high-order axial modes TE52q ( q = 2,3 ) in the region between electron gun and ca:vity, where guide magnetic field is down-tapered.
