Abstract

RF window is an important component of all high power microwave tubes and is used on the output section of the device for the propagation of RF power from ultrahigh vacuum environment to external normal pressure environment. There are different types of windows used for Gyrotron. This work presents the design & simulation of double disc sapphire window with surface cooling for 42 GHz, 200 kW Gyrotron using HFSS software and also analyzes the losses for variation in disc thickness & variation in spacing between two discs with two different coolants like FC-75 and FC-40. The minimum Insertion loss (S21) & return loss (S11) is found to be -0.01 dB & -25.20 dB respectively for disc thickness 3.2mm and optimized spacing 2.1mm of RF window with FC-40 coolant for 42 GHz Gyrotron.
