Study of interaction structure for 120GHz,1MW Gyrotron

In this paper estimation of the eigen frequency and quality factor in an interaction cavity of Gyrotron for operating mode is discussed. Eigen mode analysis for high frequency has been carried out using CST Microwave studio to have an idea about the excitation of operating modes in the interaction structure in the gyrotron. The simulation has been done using CST (MWS) for 120 GHz, 1MW Gyrotron obtained the simulated Eigen frequency as 120.142 GHz.
