A system for manufacturing a photocathode includes a cap having a first end and a second end. The first end defines a passage operable to direct an etch compound to an etch surface of the photocathode. The system also includes a support operable to releasably engage the cap to align the etch surface of the photocathode with the passage of the cap. The system also includes a plunger operable to extend through a passage in the support to secure the photocathode against the cap to confine the etch compound to the etch surface of the photocathode.
