HIGH-POWER MICROWAVE TUBE WINDOW INVESTIGATIONS

Abstract

This report gives a brief description of high-power microwave tube window problems. The emphasis in the discussion is placed on problems associated with the single-surface multipactor phenomenon. Window coating criteria and means of eliminating multipactor and multipactor-related problems are presented. Sputtering equipment and new coating and control procedures developed in this program are described in greater detail. Problems associated with the changes in the resistivities of coatings, including the effects of tube processing techniques, are discussed. Work performed on coating identification and problems associated with producing a uniform coating are described. Results of some thirty-seven experiments performed in this program are presented. Physical changes in window materials arising from multipactor are described. A new improved metalizing-window-brazing technique, which produces a strong metal-to- dielectric bond with thin metalizing layer and a minimum of penetration of metalizing constituents into the dielectric, is given, and pertinent fabrication procedures described.
