NEG coatings
Non Evaporable Getter
NEG (Non Evaporable Getter) coatings is a critical technology to maintain the ultra-high vacuum levels required in the vacuum chambers of particle accelerators, providing an efficient and low maintenance solution to avoid residual gas molecules in the beam path, that may affect the results of experiments with photons and particles accelerated close to the speed of light. Tekniker and AVS, in collaboration with TVP, develop vacuum chambers and coatings for particle accelerators. The implementation of NEG coatings in the vacuum chambers can help to reduce the maintenance operations related to pumping equipment and provides a better level of vacuum helping to reduce the operational costs while improving the quality of the experiments.
