Non-Evaporable Getter

Non-Evaporable Getter

Non-Evaporable Getter (NEG) is a powder of an Al-Zr alloy that readily forms stable compounds with active gases. Sintered onto the inner surface of high vacuum vessels, it acts as a getter or getter pump that is able to reduce the pressure to less than 10−9 Torr. The NEG coating can be applied even to spaces that are narrow and hard to pump out, which makes it very popular in particle accelerators where this is an issue.
