Development of high power microwave sources for fusion applications is limited by the availability of suitable vacuum windows in the 100 to 200 GHz frequency range. A novel vacuum window is described which uses water cooled sapphire as the dielectric. Heat removal is achieved by using thin slats of sapphire interleaved and brazed to niobium hexagonal tubes in which the cooling water flows. Analysis indicates a window 100 cm{sup 2} in area can readily pass 1 MW in the HE{sub 11} mode at 110 GHz for current experimental applications and 1 MW with a HE{sub 11}{sup 0}-HE{sub 12}{sup 0} mixture at 170 GHz, the projected ITER frequency.
