Method for manufacturing a photocathode

Abstract

A method for manufacturing a photocathode includes positioning the photocathode on a support such that an etch surface of the photocathode faces away from the support. The method includes inserting an end of the support containing the photocathode into a cap. The cap comprises a passage operable to direct an etch compound to the etch surface of the photocathode. The method also includes aligning the etch surface of the photocathode with the passage of the cap using the support. The method also includes inserting a plunger through a passage in the support to contact a surface of the photocathode opposite the etch surface of the photocathode. The method further includes securing the photocathode against the cap using the plunger to confine the etch compound to the etch surface of the photocathode.
