The existence of normal equilibrium in tokamaks with negative current in the column center

Plasma rotation is shown to remove the impossibility of the existence of “normal” equilibrium in a tokamak with reversed current. The mathematical procedure of how to overcome the peculiarities, which appear in the equilibrium equations due to current reversal, is suggested. An example of normal tok...

Description
Summary:Plasma rotation is shown to remove the impossibility of the existence of “normal” equilibrium in a tokamak with reversed current. The mathematical procedure of how to overcome the peculiarities, which appear in the equilibrium equations due to current reversal, is suggested. An example of normal tokamak equilibrium with a reversed current is constructed.
