An automation system for assembling photocathodes into vacuum tube housings is used to produce vacuum tube assemblies. Photocathodes are loaded and otherwise processed in a first evacuated chamber. Similarly, vacuum tube housings are loaded and otherwise processed in a second evacuated chamber. The first and second chambers are always interconnected as a common vessel, wherein the photocathodes from the first chamber are transferred into the second chamber by an automated transfer mechanism. Once in the second chamber, the photocathodes are joined to the vacuum tube houses in an automation process, creating the final product vacuum tube assemblies.

An evaporator for containing a second material which is to be evaporated onto a remotely located surface after a first evaporation of a first material, comprises a tubular member having crimped ends for preventing the second material from combining with the first material during the first evaporation thereof and an aperture for allowing the escape of the second material from the evaporator during evaporation of the second material, the aperture being formed on a flattened area of the tubular member.
