Experimental verification of X-point potential well formation in unfavorable magnetic field direction

Recent TCV experiments confirm the predicted formation of an electric potential well, below the magnetic X-point, in configurations with unfavorable Btfield direction (ion ∇Bdrift away from the divertor), that substantially reshapes the typical divertor E×Bflow pattern. The local charge balance ∇⋅ji...
