Abstract

Window happens to be the most critical and vulnerable component in high-power gyrotrons. For the first Indian gyrotron window, a face cooled double sapphire disc structure has been decided for delivering 200 kW power at 42 GHz. Development of sapphire machining and techniques for its UHV grade joining to metals are the major achievements so far. Optimisation of electrical and thermal parameters is in progress.
