A QUANTITATIVE STUDY OF THE EVOLUTION OF GASES FROM ELECTRON TUBES AND MATERIALS
Abstract
This work is aimed at achieving a higher degree of reliability in electron tubes through a better understanding of the kinds and quantities of gases which occur in these tubes. A bakeable, ultra-clean high vacuum system which incorporates an omegatron mass spectrometer was constructed for conducting these investigations. Several Amperex Type 5894 tubes were degassed by various schedules. The pumping speed of the ion pump was estimated for methane gas. Several difficulties with heating and operating the tube under test were resolved. The principal gas evolved during dc bombardment of this tubedrogen.
