Hickman's three-stage self-fractionating diffusion pump .

Function This is an oil diffusion pump, a type of vacuum pump that is able to attain a much higher vacuum than traditional mechanical pumps. They function as an additional stage between the system to be evacuated at one end, and a mechanical vacuum pump at the other end. Diffusion pumps are a critical technology for attaining the high vacuums required for many important 20th-century .
