IMAGE INTENSIFIER ISOCON FEASIBILITY STUDY
Abstract
Image intensifier isocons were built to test glass targets, magnesium oxide targets and aluminum oxide-nickel plug targets. Two different glasses were used, one a high resistivity glass used on previous image intensifier orthicons, the other a lead glass used for image orthicon targets. The tube with the high resistivity glass target, when operated in the orthicon mode performed on a par with standard intensifier orthicons with the same target. The performance of these tubes indicates the need for an extremely smooth, fine grained surface on the scanned side of the isocon target. The ability of the present intensifier isocon to present low light level information appears to be limited mainly by the background imperfections in the target, phosphor screen, intensifier coupling element and photosurface rather than the electron beam noise.
