Ultra-high vacuum (often spelled ultrahigh in American English, UHV) is the vacuum regime characterised by pressures lower than about 1 × 10 −6 pascals (1.0 × 10 −8 mbar; 7.5 × 10 −9 Torr). UHV conditions are created by pumping the gas out of a UHV chamber.
One langmuir corresponds to an exposure of 10 −6 Torr during one second. [1] [2] For example, exposing a surface to a gas pressure of 10 −8 Torr for 100 seconds corresponds to 1 L. Similarly, keeping the pressure of oxygen gas at 2.5·10 −6 Torr for 40 seconds will give a dose of 100 L.
