ELECTRON TUBES RADIATION RESISTANT PILOT LINE PRODUCTION.
Abstract
During this quarter all work required by the contract for delivery of Engineering Samples, items 1-1-1B and 1-1-1C, was completed with the exception of the high temperature (500C) life testing of tube types 6360, 6205, and 5886 in Alumino-Silicate glass. Pulse radiation tests were conducted. The results of this test plus those from the steady state reactor test at Brookhaven are given in Appendix II. Sealing of tube type 6205 using RF or heliarc welding techniques was not successful in improving cathode emission. Although good vacuum tight seals were obtained low emission remains a serious problem. Parts for 6080WB tubes are being fabricated to meet the pre-production quantity and delivery date. The ceramic spacers for tube type 6360 have been received and tubes assembled. High temperature bakeout (650C) on exhaust still affects cathode emission. Modifications to the exhaust equipment, considered at the end of the sixth quarter, were made during December. (Author)
