Abstract:

This report covers the fourth quarter of work under a 19-month program to conduct a theoretical and experimental investigation leading to the development of improved dielectric-to-metal seals and sealing techniques for use with output windows for high-power microwave tubes. The use of finer molybdenum, tungsten, and S-641A particle sizes in the metalizing inks employed in the sapphire-refractory metal seals was investigated. Seal sleeves of thicker copper and copper-plated stainless steel, Kovar, and nickel were evaluated for compression-band window assemblies. Author
