This paper describes design and development of single disc RF window for high power Gyrotron. The electrical design of edge cooled single-disc alumina window for 170 GHz, 1MW short pulse Gyrotron has been carried out using CST microwave studio. A diameter and thickness of the ceramic window are 90 mm and 3.16 mm, respectively, whose edge is directly cooled by water. The return loss (S11) and insertion...
In this paper investigates the design of edge cooled single-disc CVD-diamond window for 120 GHz, 1MW gyrotron. The design of RF window for 120 GHz, 1MW gyrotron has been carried out using the CST microwave studio. In 120 GHz gyrotron single disc of diameter 90 mm and thickness 2.0 mm CVD diamond window has been used in the simulation. The return loss (S11) and transmission loss (S21) of the 120 GHz...
In this paper study of cavity and window has been carried out using Ansoft HFSS for Terahertz Gyrotron. Eigen mode analysis of the cavity has been carried out at 1THz. An idea about the operating modes in the cavity of the Gyrotron and obtained the simulated Eigen frequency and field pattern of the modes. The design of window for 1 THz Gyrotron has also been carried out using HFSS. The simulated results...
In this paper, thermal and structural analyses of an RF window for a 42-GHz 200-kW gyrotron have been carried out using ANSYS software and discussed in this paper. The evaluation of the thermal and structural aspects of the window for the 42-GHz gyrotron during an extreme case of operation, i.e., at saturation, has been carried out. Temperature profiles have been obtained for different values of dielectric...
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...
