"A discrepancy in the impurity concentration, when estimated from the line radiation of H- or He-like ions, occured both in CASTOR and TCV tokamaks and could be only removed, of an impurity transport was %22ad hoc%22 included. This indicates that a model of impurity radiation has to be adopted that wil take acount of an impurity transport. The project proposes a numerical modeling of impurity radiation in the tokamak plasma to be used for interpretation of the experimental data of the ultrasoft-X-ray (USX) and vacuum-ultraviolet (VUV) impurity radiation, with the aim the time and space resolved concentration of the dominant impurities and the transport parameters to be estimated. In frame of the project, we intend to seek for a contingent link between the impurity content and the plasma fluctuations using a controlled seeding of an impurity."@en . . .
