RESEARCH AND DEVELOPMENT TO IMPROVE THE RESOLUTION OF IATRON DIRECT VIEW STORAGE TUBES.

Abstract

The width of a stored line is a linearly increasing function of the percent of saturation brightness i.e., insulator charge established by the writing beam. The slope of this function is determined by the backing electrode mesh number and the gradients on each side of the storage target. Although the resolution measured with various backing electrode meshes is nearly the same at about 5 percent of saturation brightness, it improves with increasing mesh number at higher percentages of saturation brightness. Additional improvement in resolution can be obtained by increasing the gradient between the viewing screen and the backing electrode on 750 or 1000 mesh screens. This improvement is believed to be a result of reduced transit time. (Author)
