Ultra-high vacuum - Wikipedia
WEBUltra-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.

Ultra-high Vacuum Applications - Leybold
WEBUHV is the vacuum regime characterised by pressures lower than about 10 −9 mbar (10 -7 Pa). Ultra-high vacuum conditions are necessary to reduce surface contamination in many surface analytic techniques.
Ultra-High Vacuum | LIGO Lab | Caltech
WEBUltra-High Vacuum. U.S. National Science Foundation Laser Interferometer Gravitational-wave Observatory (NSF LIGO) optical components quietly reside in a colossal vacuum chamber encompassing 10,000 cubic meters (353,000 cubic feet), with an air pressure of 10 -9 Torr, or one-billionth of an atmosphere. NSF LIGO's vacuum system is …
Unveiling the Realm of Ultra High Vacuum (UHV) Applications
WEBJul 16, 2023 · Ultra high vacuum refers to an environment with extremely low gas pressures, typically below 10^-9 torr or mbar. This pristine condition eliminates contaminants and allows for unique processes and applications that …
Ultra and Extreme High Vacuum Enabling Advanced Science
WEBWhether isolating subatomic particles or simulating the conditions of space, ultra-high vacuum (UHV) and extreme high vacuum (XHV) are at the center of the human search to understand the physical universe.
Design and Fabrication of UHV Chambers - pvcp
WEBUltra-high vacuum (UHV) by definition begins at an absolute pressure of 10-7 mbar, which means that surface outgassing becomes critical to ultimate pressure at this pressure range. The flow in the UHV is molecular, the mean free path length is more than 1 km.
A vacuum as empty as interstellar space - CERN
WEBTwo important design features maintain the ultra-high vacuum in the room-temperature sections. Firstly, these sections make widespread use of a non-evaporable "getter coating" – developed and industrialized at CERN – that absorbs residual molecules when heated.
Recent Advances in Ultra-high Vacuum Technology
WEBThe two major directions for advances in ultra-high vacuum technology are (I) the attainment and measurement of pressures below 10~10 mm Hg, and (2) the development of large ultra-high vacuum systems.
