Description
  • Znalost transportních koeficientů nečistot plazmatu a částic samotného plazmatu hraje důležitou úlohu v projektu připravovaného fúzního reaktoru; dále slouží k ověření platnosti výstupů stávajících a vyvíjených transportních modelů. Kvazi-stacionární profily plně ionizovaného uhlíku C6+ (přechod n=8-7, 529.1 nm) uvolněného ze stěn komory tokamaku TCV (R = 0.88 m, a<0.25m, BT<1.5 T) byly stanoveny pomocí aktivní CXRS (Charge eXchange Recombination Spectroscopy) diagnostiky a následně použity pro určení transportních koeficientů na osnově jedno-dimenzionálního transportního modelu. Při vysoké hodnotě parametru q95 byla pozorována akumulace nečistot způsobená spíše anomálními, než neoklasickými procesy. (cs)
  • Knowledge of the impurity transport parameters and their relation with those of the main plasma particles is important for predicting the fusion performance of a tokamak reactor and provides an element for validating advanced transport models currently under development. The radial profiles of fully ionized carbon C6+ (transition n=8-7, 529.1 nm) released from TCV (R = 0.88 m, a<0.25m, BT<1.5 T) wall tiles were measured using active Charge eXchange Recombination Spectroscopy (CXRS) [1]. A 1D impurity transport model was used to infer carbon transport parameters from the steady state profiles of fully ionized carbon. At high q95 a phenomenon of impurity accumulation of anomalous (rather than neoclassical) origin is observed.
