Abstract

An important component of the output system of gyrotrons is the RF window. It serves as a barrier between the vacuum side of the gyrotron and the output transmission line. It should withstand high power, mechanical and thermal stresses, be leak tight (≈ 10−10 Torr) and be lossless. The basic problems to be addressed for high power RF windows are power handling capability, selection of window material, thermal and mechanical stresses and their management, window flashing/arcing, and puncturing/physical damage. Therefore, care must be taken in selecting a proper window material with low loss tangent (tan δ), high thermal conductivity, suitable mechanical strength, and perfect design to minimize power reflections and absorption for better transmission.
