Abstract
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.

A system for manufacturing a photocathode comprising:
- a cap comprising a first end and a second end, the first end defining a passage operable to direct an etch compound to an etch surface of the photocathode;
- a support operable to releasably engage the cap to align the etch surface of the photocathode with the passage of the cap;
- and
- 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.
A system for manufacturing a photocathode comprising:
- a housing, the housing comprising a seating surface operable to engage a portion of the photocathode bordering an etch surface of the photocathode;
- a support operable to releasably engage the housing to align the seating surface of the housing with the portion of the photocathode bordering the etch surface;
- and
- a plunger operable independently of the support to releasably engage the photocathode to secure the seating surface against the portion of the photocathode bordering the etch surface to confine an etch compound to the etch surface of the photocathode.
A system for manufacturing a photocathode comprising:
- a housing, the housing comprising a seating surface operable to engage a portion of the photocathode bordering an etch surface of the photocathode;
- a support operable to releasably engage the housing to align the seating surface of the housing with the portion of the photocathode bordering the etch surface;
- a plunger operable secure the seating surface against the portion of the photocathode bordering the etch surface to confine an etch compound to the etch surface of the photocathode;
- and
- wherein the support comprises a threaded passage, and wherein the plunger releasably engages the threaded passage to secure the portion of the photocathode bordering the etch surface against the seating surface of the housing.
A system for manufacturing a photocathode comprising:
- a housing, the housing comprising a seating surface operable to engage a portion of the photocathode bordering an etch surface of the photocathode;
- a support operable to releasably engage the housing to align the seating surface of the housing with the portion of the photocathode bordering the etch surface;
- and
- a plunger operable secure the seating surface against the portion of the photocathode bordering the etch surface to confine an etch compound to the etch surface of the photocathode, wherein the plunger comprises a reduced diameter portion operable to contact a surface of the photocathode opposite the etch surface, and wherein the support comprises a recess operable to provide deformation relief of the reduced diameter portion.
