Du Mont Laboratories finalized basic and component designs and developed a method for pre-testing the electron gun design. Historical test evaluation data indicates that the major cause of rejections of tubes similar to the 12BCP19 are the result of mis-alignment of electron gun components. Electron gun assemblies for this program will be individually tested in 12BCP19 blanks before sealing into a fiber optic tube. Prior to fabrication of the fiber optic faceplate tubes, two experimental units with plain glass dummy faceplates will be processed through all operations, thereby proving reliability of manufacturing operations. Preliminary studies and reviews disclosed limitations were imposed by the fiber optic supplier, also available fixtures for fiber optic faceplate fabrication limit the faceplate diameter to 11-78 inches maximum.
