Abstract
A weakly tapered interaction cavity has been designed to excite TE03 operation mode at the fundamental harmonic number for 42 GHz, 200 kW gyrotron. A software code GCAVSYN has been developed to synthesize cavity geometry and selection of operating mode. The cold cavity analysis and beam-wave interaction were carried out using commercially available PIC code MAGIC. An axial output power above 200 kW has been achieved at guiding cavity magnetic field 1.61 T.
