DEVELOPMENT OF AN IMPROVED JAN 6299.

Abstract

The purpose of this contract is to evaluate certain areas of advanced tube manufacturing techniques and apply them where feasible to JAN 6299 to result in a more reliable and better performing tube. The objective requirements for the improved tube are Signal Corps Technical Requirement SCS-90 (Improved JAN 6299) and operation at a tube temperature rating of 225 C. A summary of the status of the following areas is presented: (1) improved alignment, concentricity and ceramic strength; (2) improved anode to ceramic seal; (3) temperature control at exhaust; (4) improved application of cathode coating; (5) improved cathode mounting; (6) improved processing for higher temperature operation; (7) improvement in humidity testing; (8) improved exhaust fixturing; and (9) extended life test and tube failure analysis. The conclusions reached on the failure mechanism during humidity testing are also presented. (Author)
