Abstract

In this paper, the electrical design of the water-edge-cooled single-disk chemical-vapor-deposited-diamond window for the 120-GHz 1-MW gyrotron has been carried out using the CST Microwave Studio. The return loss (S₁₁) and transmission loss (S₂₁) of the 120-GHz gyrotron window have been obtained as -37.3 dB and -0.04 dB, respectively. The thermal analysis of the RF window for the 1-MW gyrotron has also been carried out using ANSYS software and discussed in this paper. The thermal analysis of the window, during extreme case of operation, has been carried out. The temperature range on the disk surface has been found to be 50°C-150°C.
