Its construction and principle of operation is simple. It consists of a titanium filament through which a high current (typically around 40 A) is passed periodically. This current causes the filament to reach the sublimation temperature of titanium, and hence the surrounding chamber walls become coated with a thin film of clean titanium.
Worthington Industries was founded in 1955 by John H. McConnell, a steel salesman.McConnell saw an opportunity for custom-processed steel and purchased his first load of steel by borrowing $600 against his 1952 Oldsmobile.
Ion pumps; Titanium sublimation pumps; Non-evaporable getter (NEG) pumps; Cryopumps; Diffusion pumps, especially when used with a cryogenic trap designed to minimize backstreaming of pump oil into the systems. Turbo pumps and diffusion pumps rely on supersonic attack upon system molecules by the blades and high speed vapor stream, respectively.
Getter pump or sorption pump In laboratory vacuum systems, the bulk NEG getter is often held in a separate vessel with its own heater, attached to the vacuum system by a valve, so that it can be replaced or renewed when saturated. [8] Ion getter pump Uses a high voltage electrode to ionize the gas molecules and drive them into the getter surface.
