Abstract

The main functions of ITER Gas Injection System (GIS) are to provide gas fuelling for plasma, wall conditioning operation, and neutral beam injectors. Dedicated manifold, which contains independent tubes for H₂/D₂, H₂, T₂, ⁴He/³He, N₂/Ne, Ar and evacuation, is the key part of gas injection lines. It shall deliver gases from the tritium plant to the various fuelling systems. This paper presents an overview of GIS manifold design, especially introduces the solution of penetration structure and routing of manifold from concept design point of view.
