Abstract:

The over-all tube length and weight of the BL-223 was decreased. Attempts were made to eliminate the expensive copper-clad molybdenum material used in the anode vanes, but the tests results proved negative. An investigation was made into a coaxial output line using ceramics in place of glass. The tuner drive assembly was improved by eliminating the tuner locking screws. The envelope material was changed from monel to kovar. The external end of the cathode assembly was shorted and the glass was replaced with ceramic. A new potting technique was accomplished, reducing costs of labor and materials. The tube shield was shortened, simplified and reduced in cost. A summary of the tubes assembled, problems encountered, and representative life tests are presented. Author
