Industry & Occupation
Classification
Summary
Manufacturing technician who handles everything from assembling components of electron tubes (phototubes) that convert light to electric current, to vacuum sealing and performance inspection.
Description
Phototube assemblers assemble components such as photocathodes (cathodes), anodes, and glass electrodes, use vacuum pumps to create a high vacuum state inside the tube and seal it. After assembly, they measure and inspect electrical characteristics such as sensitivity and dark current, and ship products that meet standards. Since they handle fine parts, dexterity and high attention to detail are required, and work in clean room environments is common.
Future Outlook
Demand for phototubes is declining due to the spread of semiconductor optical sensors, but they continue to be used in special applications. Skills in vacuum technology and precision optical component manufacturing can be utilized in other fields.
