Fusion News: Phys Org- Nuclear Fusion: Jülich’s role in ITER
Jülich Institute of Energy and Climate Research and the Jülich Central Institute of Engineering will be designing a measuring system for the fusion experiment ITER. The measuring system will determine the composition and temperature of the plasma in the vacuum vessel. As reported by Phys Org in the article “Nuclear Fusion: Jülich’s role in ITER:”
Once designed by the consortium, the core plasma CXRS system will be procured by F4E and assembled into a port plug, to be installed in an inset at the upper edge of the vacuum vessel. The consortium gained a significant knowledge related to this diagnostic through R&D tasks funded in the past years by the European Fusion Development Association (EFDA) and by the Federal Ministry of Education and Research (BMBF). In particular, deployment of such a system under the extreme conditions that will be encountered in ITER necessitates complex development work and tests. Indeed, temperatures exceeding 100 million degrees Celsius are expected within the vacuum vessel and the associated plasma radiation, neutron flux, and electromagnetic forces all impact significantly on the design choices for components. In addition, maintenance and repairs are usually only possible using remote-controlled tools or robots.
