Abstract
The average values of the scrape-off layer (SOL) plasma quantities of FTU, density, temperature e-folding lengths are studied as a function of the main plasma parameters and satisfactorily compared with 2D model predictions. The cause of their poloidal asymmetry is investigated and attributed to the variation of the magnetic line connection length. A self consistent model of the FTU plasma, 0D in the core and 1D in the SOL, can reproduce the main features of the impurity production and power radiation in FTU.File in questo prodotto:
