Abstract:

The intent of the study program covered by this report was to develop improved dielectric-tometal sealing techniques specifically for use with output windows for high-power microwave tubes. Four types of seals and six types of dielectric materials were investigated. Throughout the study a high-alumina-oxide content dielectric material commonly employed in window fabrication was used assa reference material for comparative evaluation of sealing techniques. Objectives of the program included development of seals that would be vacuum tight when baked at 700 Centigrade, or a minimum of 450 Centigrade, and would remain vacuum tight after being cycled 1000 times between 20 and 125 Centigrade.
