Ceramic and single crystal windows for the transmission of high average power (>50 kW) microwave and millimeter wave tubes such as the gyrotron are a key limitation in practical tube development. Thermal stresses can be calculated by computer modeling, but various assumptions lead to large uncertainties. To determine the actual window condition, a technique for monitoring the temperature distribution over the window surface with an ir camera while the gyrotron is in operation has been developed. The ir camera views the window through a perforated waveguide wall and serves both as a guide for the safe operation of the gyrotron, as well as an aid in the analysis of new window designs. The technique is applicable to many types of high average power microwave and millimeter wave tubes.
