ADVANCED PROCESSING TECHNIQUES FOR CAMERA TUBES.
Abstract
Studies have been continued in the application of remote processing techniques as directed toward camera tube fabrication. Advantages of the subject method of photocathode formation are as follows: 1. Ability to remotely process photocathodes on substrates without exposing component tube assemblies to contamination of alkali vapors normally associated with conventional tube processing techniques. 2. Means of forming several photocathodes in the processing chamber and thereby permitting the selection of the photosurface of highest sensitivity for sealing to the electron device. 3. Facility of providing an extremely high vacuum during the time of photocathode transfer and sealing to the main tube assembly. 4. Elimination of photocathode formation components from within the envelope, allowing tube designs of more compact nature. Within the period including June through September 1964, efforts were directed toward fabrication of photodiode and nonimaging photomultiplier configurations, utilizing S-20 and S-21 photosurfaces.
