An internal view of the vessel with a complete metallic “ITER-Like” wall of beryllium and tungsten. Taken just before pump down, at the end of maintenance shutdown in May 2013, which was mainly aimed at removing a selection of tiles for surface analysis of their performance during the first experimental campaign with metallic walls (2011-2012).
Protruding vertical “stripes” of tiles at various points around the vessel are beryllium limiters, the dull grey tiles in the lowest part of the vessel (known as the divertor) are tungsten.
Taken from Octant 1, three arrays of heating antennae are visible on the right hand outer walls, and one array on the left.
