CHROMATIC AND SPHERICAL ABERRATION IN ELECTROSTATIC LENSES.
Abstract
High resolution cathode-ray display devices demand focusing systems that reduce total aberration to the lowest possible value. Magnetic focusing systems have proven superior to electrostatic systems with respect to total aberration, but their size, weight, and power requirements restrict their use. Hence considerable effort is being put into high resolution electrostatic focusing systems. The two limiting aberrations, spherical and chromatic, are analyzed in this thesis for four types of electrostatic lenses and the results compared. (Author)
