Abstract : Advanced assembly techniques to be used in making camera tubes were investigated. Photocathode processing is being done in a vacuum bell jar assembly station. S-11 and S-20 surfaces are made on glass sub-strates, transported by means of manipulators to an assembly position and sealed into a complete tube. Sensitivities range to 30 microamperes per lumen for S-11 to 100 microamperes per lumen for S-20 surfaces. Considerable loss of sensitivity occurs during the transfer operation. Gas analysis is being done to identify harmful gases present, in order to eliminate loss of sensitivity. Indium seal quality is very good with checks made by mass spectrometer and attached ion gauge/pump. Preliminary work on cold metal to glass seals is described. (Author)
