Abstract
An experimental yoke consisting of four sets of independently excited coils has been made. The field distribution of the experimental yoke can be controlled to approximate the theoretically calculated ideal fields, which produce minimum aberrations for certain specified working distances, field coverage, and beam convergence angle. The aberrations that would be produced by the experimental yoke are calculated and compared with those of the ideal field.
