During the installation, the sensors are welded to a small stainless-steel tube, called “boss” which itself is welded to the vacuum vessel outer shell. The sensor housing needs to be aligned precisely (<1°) with both, the radial and the toroidal axis before the housing is welded to the “boss”. The jig contains a dual-axis inclinometer, which is to measure both, the rotation angle along the boss radial axis and the angle in the toroidal direction. Radial and toroidal misalignments of the sensors need to be corrected prior to the welding of them to the “boss” using the installation jigs supplied by GMES Engineering Ltd.
GEMS supplied 10 alignment jigs for the ITER Organisation which are used for mounting 60 steady state sensors for the outer surface of 3 sectors (#2, #5 and #8) of the ITER tokamak.
Vacuum vessel sector #8 can be seen in Figure 4. After inspection, the sector will be equipped with fasteners, instrumentation and diagnostics before moving it to a vertical position in sub-assembly tooling.
GEMS Engineering is deeply involved in and fully devoted to the success of the ITER project. As a result, our main reference works are in connection with ITER, and - more closely - to its diagnostic systems.
The ITER device, currently under construction in the south of France, will study the potential of controlled nuclear fusion to provide energy for mankind. In order to study the behaviour of this device, a set of monitoring systems (referred to as Diagnostics) is required. These Diagnostics will provide the information required to understand the performance of the device.
