Abstract: A stigmatic, crossed-field velocity filter for nondeflection purification of an ion beam employs shaped electrodes to increase the uniformity of the electric field and employs shaped magnetic pole pieces to produce a nonuniform magnetic field for stigmatic passage of the selected ion species through the filter.
