Abstract :
A previous paper described the design of a vacuum window proposed for use in the WR-1800 waveguide. This work details the results of a high power test of the completed prototype window. The window passed all design goals when operated in a short-circuited load. For the case of a matched load, the travelling wave power reached a maximum of 260 kW CW with vacuum bursts as a limiting factor. In addition to the results from the high power tests, some results from low power tests using a network analyzer are given. Some general conclusions are drawn concerning the design of vacuum windows in a rectangular waveguide
