DESCRIPTION: With the introduction of tungsten plasma-facing components in 
 ITER and in other machines\, the accurate reconstruction of the tungsten (
 W) concentration distribution in the plasma has become a critical issue. I
 ndeed\, a very low concentration of W in the plasma core can induce a rapi
 d loss of confinement and lead to a disruption or loss of performances. Am
 ong the various diagnostic approaches\, the use of soft X-ray measurements
  appears particularly promising. X-ray spectral data can provide access to
  key plasma parameters\, including the magnetic axis position\, the electr
 on temperature\, and the impurity concentration along with its spatial dis
 tribution\, following tomographic inversion. Several techniques for recons
 tructing and validating the tungsten distribution\, including recent IA ap
 proaches are presented with some application on the WEST tokamak that will
  be introduced at that occasion.\nVortragender: Dr. Didier MAZON
