Abstract:

This report includes MECHANICAL COLLIMATION OF IATRON IMAGE SECTION, by R. Clayton. 27 Apr 62 Research rept. no. 169 ON THE DESIGN OF AN IATRON WITH SOLENOIDAL FOCUS FIELD, by R. H. Clayton. 7 June 62, rev. 19 June 62 Research memo. no. 363 Elemental aperture lenses in the storage mesh of Iatron display storage tubes form highly divergent cones of flood electrons in the phosphor region which greatly reduce resolution at high brightness levels. Solution of this problem may be achieved, in general, by 1 weakening aperture lenses, 2 reconverging elemental cones, and 3 gross electrostatic or magnetic focus of the entire storage screen. The general solutions listed above were expanded into specific approaches, and an estimate of the relative promise of each was attempted. The technologies which presently limit mechanical collimation are described. Gross magnetic focusing options are explored theoretically. Both theoretical and experimental data are presented relevant to electrostatic microlens design. A technology of mesh thickening is described in detail. Author
