Fusion glossary

V

Pumps which remove gas, usually air, from a chamber, leaving it under vacuum. A variety of types are used in ITER, depending on the quality and degree of the vacuum needed.
The vacuum vessel establishes the confinement barrier in a tokamak and limits the heat flux to the toroidal field coils. It provides low-impurity volume for the reacting plasma.
