Abstract:

An examination of the gases in operating gridded-power traveling wave tubes was undertaken with a view to determining the causes of tube failures. Individual tube components, under conditions simulating an operating tube, were also investigated to learn the source and behavior of gases present. Gas analyses were made on both the operating tube and the tube components by means of a permanently attached omegatron mass spectrometer. Data are presented on two types of traveling wave tubes, one KIC getter, a sub-assembly gun-tester and coated heater coils. For knowledge of the total gas content of a material which can be released upon heating, a hot extraction method was used in conjunction with a commercial mass spectrometer. Kovar tube components were studied in this manner. Author
