2nd vacuum vessel sector from Korea
The nine 40-degree sectors required to form the °ÄÃÅÁùºÏ²Ê¸ßÊÖ toroidal chamber are largely similar, differing only in the details relevant to their position in the circular arrangement and interfacing components.
Like its predecessor, sector #1(7) will go through a series of operations in the Assembly Hall, such as the installation of diagnostics and instrumentation, before it is upended and moved to the sub-assembly tooling to form the second of the °ÄÃÅÁùºÏ²Ê¸ßÊÖ Tokamak sub-assemblies.
* Readers will have seen this sector referred to as #7 in past articles. In fact, sectors #1 and #7 (both supplied by Korea) are nearly identical. It was decided to install Korea's second sector (#1) in the place of #7 in the assembly pit at °ÄÃÅÁùºÏ²Ê¸ßÊÖ—hence the name "#1(7)"—in order to accelerate the assembly of the torus chamber. The sectors in positions #6 and #7 in the assembly pit will be the first of nine to be welded together.
