Nuclear physics experiments performed at the Contin-uous Electron Beam Accelerator Facility (CEBAF) at Jefferson Laboratory (JLab) require highly polarized electron beams, produced from strained super-lattice GaAs/GaAsP photocathodes. To prolong the photocath-ode operational lifetime, the photogun and adjoining beamline should be maintained at the lowest possible pressure. This document describes a Wien-filter spin manipulator with Penning traps incorporated along the length of the high voltage electrodes. For some spin set-tings, the Wien filter acts as an ion pump. Although the Wien filters at CEBAF are relatively far from the photo-cathode, a Wien-filter spin manipulator with distributed pumping could serve to improve photocathode operating lifetime.
