In this paper, the design of a triode-type magnetically tunable magnetron injection gun (MT-MIG) is presented for 1-MW 110-, 120-, and 127.5-GHz-frequency gyrotrons with the various operating modes. Some basic equations relevant to the problem available in the literature have been used to obtain the preliminary design. Computer simulation has been performed by using the commercially available code...
In this paper Eigen mode analysis has been carried out using Ansoft HFSS for high frequency 120 GHz, 140 GHz, 170 GHz, 503GHz and 1000 GHz gyrotron cavity. Eigen mode analysis has an idea about the excitation of the operating modes in the cavity of the gyrotron and obtained the simulated eigen frequency and field pattern of the modes. The CPU time on Pentium-4, 2.99 GHz system with 4 GB RAM was less...
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...
