ITER Vacuum Vessle and Cryostat Image

Highlighted in pink: Vacuum Pumping and Pellet Injection Systems.

The US will contribute 100% towards the roughing pumps and vacuum auxiliary system.

The ITER tokamak, cryostat, and auxiliary vacuum chambers must be evacuated prior to and during operations. The roughing pump system exhausts the torus and neutral beam injector cryopumps, service vacuum, and cryostat. This system will utilize a matrix of pump trains with various technologies to match specific vacuum system requirements, including tritium-compatible backing pumps for torus and neutral beam cryopumps.

The vacuum auxiliary system consists of valves, pipe manifolds, auxiliary pumps, sensors, and controls. The torus and neutral beam injector vacuum manifolds of this system need to be tritium compatible.
