Discussion History

Vacuum System

Assembly

Pumps the chamber down to the low pressure at which ice sublimes, typically tenths of a millibar, and holds it there against the small leak and outgassing loads. A roughing pump and a booster pump work in series. A full specification article for this item is being written. Meanwhile its bill of materials and connections are below.
