DESIGN, DEVELOP AND FABRICATE MINIATURE, FIBER OPTIC FACEPLATE CATHODE RAY TUBES.
Abstract
Efforts were continued on the development of miniature fiber optic faceplate cathode ray tubes. The bell jar vacuum system demountable setup was completed and one assembly using a stock gun was made to check the electron optics of the ballistic and post acceleration region. A second assembly was made using a stock gun and a graded pitch spiraled post accelerator. A third assembly was made using a gun designed with regard to its electron optical performance. The ballistic and post accelerator of the second setup were used. Two sealed off gun test tubes and three sealed off phosphor test tubes were also made. The conclusions were as follows: (1) a uniform field in the ballistic region was desirable; (2) a graded pitch spiral in the post acceleration region gave divergence which improved the deflection sensitivity as full scan; (3) some pattern distortion resulted from lack of field matching between the ballistic and post acceleration region; (4) the overall system with the gun designed for this tube should be capable of giving an undeflected spot size of 0.0018 inches; and (5) P28 phosphor was not a good candidate for high resolution work.
