Contribution of E→×B→ drifts and parallel currents to divertor asymmetries

A systematical study of E→×B→ drift and parallel current effects is reported based on the analysis of the simulations by B2SOLPS5.2 transport code. It is demonstrated that divertor asymmetry for connected double null (CDN) configuration is established due to poloidal E→×B→ drift and parallel thermal current. For single-null configuration the existing asymmetry is amplified by account of these effects.
