A 120 GHz gyrotron with 1 MW RF power and an electronic efficiency of 30% is designed. The beam voltage is 80 kV, the beam current is 40 A andt he operating mode is TE22,6 and the gyrotron is designed for radial output power of 1.0 MW. Clearly, the spent electron beam has 2.2 MW power coming through input beam power after power growth in the device as waste power and that must be dissipated on the collector wall. To overcome the problem of thermal loading, the electrical design of single stage depressed collector with non-adiabatic magnetic field has been carried out. The water cooling duct has been modeled using multi-physics software. Further, the thermo-mechanical analysis is carried out to optimize the design tolerances.
