Computational assessment of effects of electric fields and currents in tokamak edge plasmasFunded under: EAEC-FUSION 12C
The importance of the edge electric field has been pointed out in both divertor and limiter configurations. In order to investigate the impact of biassing on scrape-off layer profiles the B2 code has been extended to compute electric fields, electric currents and diamagnetic particle drifts. In this paper the effect of the addition variables for grounded, floating and poloidally biassed divertor plates is investigated for a low power divertor configuration. In addition, the introduction of a neoclassical expression for the radial current density provides the opportunity to obtain the electric potential inside the last closed flux surface.
