Abstract
A system (10) for manufacturing a photocathode includes a housing (12) having a first end and a second end. The first end of the housing (12) is operable to be coupled to a vacuum chamber (22). The system (10) also includes a drive support (20) disposed within the housing (12). The system (10) includes a shaft (14) disposed within the housing (12) and a ladder (16) coupled to the shaft (14). The ladder (16) includes at least one rung (140) to retain the photocathode. The system (10) further includes a drive system (18) supported by the drive support (20) within the housing (12). The drive system (18) is coupled to the shaft (14) and is operable to translate the shaft (14) relative to the housing (12) to position the rung (140) of the ladder (16) at a predetermined location within the vacuum chamber (22).
