CERN experts have significant expertise across a range of thin film coating techniques for producing High & Ultra-High Vacuum, particularly Non-Evaporable Getter (NEG) thin film coatings. NEG coatings are produced by sputtering an alloy of several selected metals onto a vacuum chamber wall. When activated by heating, the NEG chemically reacts to reduce the amount of gas in the vacuum chamber. NEG coatings also block the outgassing of the underlying vacuum chamber walls.
CERN experts can provide consultancy, training and licensing of proprietary CERN techniques for the application of NEG coatings.
Consultancy, training and licensing of proprietary CERN techniques in:
- Production of NEG thin films (vacuum, sputtering, surface preparation, adhesion)
- Preparation of sputtering targets
- Coating of vacuum chambers
- Monitoring of NEG coatings activation by XPS
- Measurement of vacuum performance of NEG coatings
- Use of MolFlow software for vacuum calculations and thin film thickness profiles
