ELECTRON BEAM TECHNIQUES FOR FABRICATION AND ASSEMBLY OF PARTS FOR ELECTRON TUBES.
Abstract
Six engineering sample tubes (four 6914A and two 6544 tubes) were successfully fabricated using the electron beam welding facility which has been established. Five preproduction tubes (four 6914A and one 6544) were successfully fabricated using the electron beam welding facility and partially tested on the approved testing facilities. For fabrication of tubes with internal photosensitive surfaces, it is necessary to prevent contamination of the photo surfaces due to oil backstreaming from the oil diffusion pump of the electron beam facility; this was accomplished by installation of a liquid nitrogen baffle on the diffusion pump.
