Probing f(e)(v) by Thomson scattering on W7-X
Thomson scattering is a widely used standard diagnostic for T(e), n(e) measurements in fusion plasmas. The Thomson diagnostic planned for W7-X provides for the first time, sufficient access to the vacuum vessel to probe several scattering geometries, allowing for scattering vectors parallel, perpendicular, and oblique with respect to the magnetic field. Furthermore, a detection system with high spectral resolution is foreseen so that there will be a good chance to reconstruct the 2-dimensional electron distribution and determine whether f(e)(v) is Maxwellian or not.
