The Fundamentals of High, Ultra & Extreme High Vacuum
WebJun 25, 2024 · Ultra-high vacuum (10-7 mbar to 10-12 mbar) Extreme high vacuum (less than 10-12 mbar) In rough- and medium vacuum most gas molecules are within the volume of the vacuum chamber, whereas in ultra-high vacuum (UHV) and extreme high vacuum (XHV) most of the remaining molecules will be on or in the chamber walls respectively. … Ultra-high vacuum (UHV) is the vacuum regime characterised by pressures lower than about 100 nanopascals (1.0×10 Pa; 1.0×10 mbar; 7.5×10 Torr). UHV conditions are created by pumping the gas out of a UHV chamber. At these low pressures the mean free path of a gas molecule is greater than approximately 40 km, so the gas is in free molecular flow, and gas molecules will collide with the chamber walls many times before colliding with each other. Almost all molecular interaction… citizen application for minors
