Abstract
A system for manufacturing a photocathode includes a housing and a retainer disposed within the housing. The retainer includes a seating area operable to receive a first surface of the photocathode. The retainer is operable to independently translate relative to the housing along an axis. The system also includes a weight enclosed within the retainer. The weight is operable to provide a substantially uniform pressure across a second surface of the photocathode as the housing translates across a polishing pad substantially orthogonal to the axis.
