Abstract

In this paper investigates the design of edge cooled single-disc CVD-diamond window for 120 GHz, 1 MW gyrotron. The design of RF window for 120 GHz, 1 MW 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 gyrotron window have been found -40.0 dB and -0.02 dB respectively. Thermal analysis of single disc rf window has also been carried out using ANSYS software for high power gyrotron. The temperature range on the disc surface has been found to be 50°C-150°C.
