“…13,14) Here, in case of 670 GHz gyrotron with the output power around 300 kW, TE 25;10 mode is analyzed in terms of mode selection parameters such as space charge effect (discussed in x4), the ohmic wall loading, the start oscillation current, etc., by using the in-house developed code GCOMS. 15,16) Particle-in-cell (PIC) numerical approach based code MAGIC is used in the beam-wave interaction simulations. 17) Parametric analysis is also performed considering the power and efficiency as main parameters.…”

In this article, a feasibility study of 300 kW RF power generation with TE25,10 (transverse electric) operating mode for 670 GHz gyrotron is presented. The beam-wave interaction computation and power growth at fundamental harmonic are carried out by using the particle-in-cell code MAGIC. The beam current, beam voltage and magnetic field at cavity center are optimized for the efficient beam-wave interaction, which are 14 A, 70 kV, and 26.34 T, respectively. The parametric analysis is also carried out to provide the flexibility in the actual fabrication of the device. It is found that more than 300 kW power generation is possible at TE25,10 operating mode.

“…The code has been used successfully in the beam-wave interaction computation for low power as well as high power fusion gyrotrons [21][22][23]. The code includes powerful algorithms to represent the incoming and outgoing waves, the particle emission processes, the electromagnetic fields, and relativistic particle trajectories [24].…”
