Production of 6080WB, 6360 and 6205 tubes in aluminosilicate glass stems and bulbs has continued. Additionally, 5886 tubes have been prepared by means of pinch press sealing. High temperature life testing 500C bulb temperature has continued on the 6080WB aluminosilicate tubes, eight having now successfully completed 500 hours of operation. Ten conventional glass 6360 tubes were high temperature life tested to destruction. The test then started on 6360 and 5886 tubes of aluminosilicate glass, and both are now continuing. The 1000 hours steady-state nuclear radiation exposure test has commenced on representative samples of all four tube types in both conventional and alumino-silicate glass 40 tubes, total. Bids have been solicited from interested manufacturers for a second dual exhaust system. Considerable engineering time has been devoted to the problem of obtaining better yields on the 5886 and 6205 types. Author
