X-UV spectroscopy for nuclear magnetic fusion diagnostic
CEA/Institut de Recherche sur la Fusion Magnétique, 13108 Saint paul Lez Durance Cedex, France
Magnetic fusion research is on the way to face a major challenge with the realization of the International Thermonuclear Experimental Reactor (ITER), which aims to demonstrate its technological feasibility. Given the range of temperatures encountered in fusion plasmas, X-UV spectroscopy has become a mandatory diagnostic tool for such plasma experiments. Various parameters such as impurity densities, ion velocities, electrons and ions temperatures are inferred through analysis of specific spectral lines or continuum levels. The ITER project imposes however new constraints due mainly to the nuclear environment and requires also new technological developments.
