Abstract: In this paper, RF behavior studies of a 2MW triangular corrugated coaxial cavity gyrotron is presented for the operating frequency of 283 GHz to explore the possibility of multi-frequency operation in an already proposed dual regime gyrotron (220/251.5 GHz). The cavity mode for the 283 GHz operation is chosen as TE62,38. Cold cavity analysis, mode competition studies and self consistent single mode calculations are carried out for this operating frequency. Time dependent multi-mode calculations are performed to verify power growth in the desired mode and the possibility of power in the competing modes. Startup analyses are carried out using the electron beam parameters obtained from the electron gun design studies for both partial and complete space charge neutralization cases. These studies confirm that 2MW, continuous wave (CW) operation can be obtained at all the three operating frequencies (220/251.5/283 GHz) in the proposed coaxial cavity gyrotron. © 2018 IMA.
