Roadmap on Quantum Sensors for Vacuum Metrology
D. S. Barker, J. L. Booth, S. P. Eckel +7
We describe how laser-cooled and trapped alkali-metal atoms have been used as pressure sensors in the high- and ultra-high-vacuum regimes operating with relative uncertainties of j…
Electrons on a straight path: A novel ionisation vacuum gauge suitable as reference standard
Karl Jousten, Matthias Bernien, Frédéric Boineau +7
The consortium of the European project 16NRM05 designed a novel ionisation vacuum gauge in which the electrons take a straight path from the emitting cathode through the ionisation…
Investigation of the effects of valve closing in a static expansion system
Thomas Bock, Matthias Bernien, Christian Buchmann +2
The precise measurement of the pressure of the gas enclosed in the starting volume of a static expansion system is important for achieving low measurement uncertainties. This work…
Total and Partial Pressure Measurement
Karl Jousten
Total pressure gauges are used to measure the level of vacuum in a system independent of the gas species. Partial pressure analysers measure the occurrence of each gas species sepa…
