A Broad-Band Glass-to-Metal Coaxial Vacuum Seal

Abstract

The design procedure for a broad-band glass-to-metal seal is described, and experimental-results are presented for a structure examined over the frequency range of 100 to 11,000 Mc. The seal described is capable of operating at bakeout temperatures as high as 450°C, with higher temperatures being attainable by the use of other materials.
