The effect of B(T) reversal on the asymmetries between the strike zones in single null divertor discharges : Experiment and theoriesFunded under: FP3-FUSION 11C
The present paper reviews experimental data and examines physical mechanisms which redistribute density between the inner and outer divertor branches and, consequently, affect temperature and power deposition asymmetries between the two strike zones in the single null divertor configuration. Amongst these is the radial ExB drift caused by the T(e) drop along the field lines towards the target and mechanism of momentum transfer into the SOL due to edge toroidal rotation. These two mechanisms compress the plasma at the inner side in the normal B(T) configuration and at the outer side when the B(T) is reversed.
