Abstract : The purpose of the work undertaken by this study program was to pursue theoretical and experimental investigations leading to the development, fabrication and testing of windows with bandwidths up to 25% and capable of transmitting 250 kilowatts cw, X-band power. Considerations of bandwidth and power requirements limited fabrication of test models to windows using single and double discs and self resonant block windows. The program requirements were more than satisfied by the high power testing to 275 kilowatts of a single crystal sapphire disc windown. In all, three different sapphire windows were tested without window failure to powers of 250 kilowatts or more.
