Ultra-high vacuum - Wikipedia
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.
Ultra-High Vacuum | LIGO Lab | Caltech
Ultra-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 one of the ...

A vacuum as empty as interstellar space - CERN
Two 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.
Ultra-high Vacuum Applications - Leybold
UHV 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.
Design and Fabrication of UHV Chambers - pvcp
Ultra-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.
Unveiling the Realm of Ultra High Vacuum (UHV) Applications
Jul 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 are crucial in various industries.
Ultra-High Vacuum Techniques - an overview - ScienceDirect
Ultra-High Vacuum Techniques involve creating an environment with extremely low pressure to study surfaces and materials with high precision. These techniques are essential for preparing well-ordered surfaces in chemistry research, especially for …
