Paper Abstract

This report describes the general theory and design of an ultra high resolution, film recorder CRT which was developed at Tektronix, Inc. The electron gun utilizes a unique pre-focusing scheme to significantly reduce aberrations in the final focusing lens, thus yielding a spot of less than .001" (1 mil) at the half power point (50%) with a beam current of 10 μA. The non-aluminized, fine particle phosphor screen was developed to minimize spot growth and maximize luminance output, while meeting stringent target defect specifications.
