The contractual work specified under Phase II has been continued. Production of alumino-silicate stems for the three types, 6080WB, 6360, and 6205, has continued, utilizing the conveyor furnace and cracked city gas, with satisfactory yield. Equipment necessary for this phase has been completed and evaluated. Tubes of all four types have been sealed-in and processed on the dual vacuum exhaust system, being baked at 800 C. Exhaust schedules are being evaluated. Tubes thus exhausted have been based as necessary, aged, and tested and aging schedules are being evaluated. High temperature life tests 500 C bulb temperature have been started on 6080WB and 6205 and improvements applied to the tube design and or processing as a result of this. Nuclear radiation testing facilities have been scheduled for both pulsed and steadystate operation of the tubes as specified in the contract. Author
