 The ZAO alloy has demonstrated excellent performance as a vacuum pumping material for a future nuclear fusion plant demo. It has shown a significant improvement over conventional getter materials with a lower pumping speed and better repeatability. Additionally, it has been found to be isotope independent, which means that it can be used in any environment without worrying about the type of hydrogen being pumped.
