OutgassingRaten
OutgassingRaten is an uncommon rendering of the term outgassing rate, used in vacuum science and materials engineering. The standard term is outgassing rate, sometimes expressed per unit area as q'' or as a total rate Q for a chamber.
Definition and units: The outgassing rate per area, q'', is the amount of gas released from a
Causes and factors: Outgassing primarily arises from desorption of adsorbed water, hydrocarbons, and other volatile species
Measurement and management: Outgassing is measured by methods such as rate-of-rise tests, where the pressure increase
Significance: In vacuum systems, outgassing sets the achievable base pressure, affects surface contamination, and can degrade
