The RF behavior of high power, triple frequency (170-, 127.5-, and 85GHz) gyrotron for fusion application is presented in this paper. The operating mode selection is discussed in detail for each corresponding frequencies and TE34,10, TE25,8 and TE17,5 modes are selected as the operating mode for 170GHz, 127.5GHz and 85GHz operation of the device, respectively. The interaction cavity geometry and beam...
The design of the interaction cavity of a 170 GHz gyrotron operating in the TE 34,10 mode is presented in this article. An in-house developed code GCOMS and Particle-in-Cell (PIC) code MAGIC are used for the mode selection and beam–wave interaction simulations, respectively. The cold cavity analysis and beam–wave interaction computation are carried out to analyze the eigenmode and output power,...
In this paper the design of interaction cavity for 170GHz, 1MW gyrotron is presented. An in-house developed code GCOMS has been used for operating mode selection and mode competition. For 170 GHz, 1 MW gyrotron interaction cavity TE28,7 mode excite as a operating mode at the fundamental harmonic number. The Electromagnetic simulator-MAGIC, a Particle-in-Cell (PIC) code has been used for the cold cavity...
A weakly tapered interaction cavity has been designed to excite TE22,6 operating mode at the fundamental harmonic number for 120 GHz, 1 MW gyrotron. A MATLAB code has been developed to synthesize cavity geometry and selection of operating mode. The cold cavity analysis and the beam-wave interaction were carried out using the commercially available PIC code MAGIC. The output power above 1 MW has been...
