PRODUCTION ENGINEERING MEASURE FOR POLYOPTIC SEALING OF HYDROGEN THYRATRON TUBES
Abstract
Life tests of automatically sealed and exhausted 7190 polyoptic hydrogen thyratrons continued. Several of the 75 required hot ring, trolley technique, polyoptic tubes were placed on life test. As a result of the experience gained in fabricating these tubes, additional effort was placed on learning the limiting tolerances to be adopted for the tube parts, processing, and fixtures. High temperature bake polyoptic seals were attempted in exploratory experiments to evaluate the use of envelope glass of a higher softening temperature than that of the stem. (Author)
