The effect of the inductive electric field on ion poloidal rotation in all collisionality regimes for the primary ions in tokamaks
- Institute of Plasma Physics, Chinese Academy of Sciences, Hefei, 230031 (China)
The expression for the poloidal rotation velocity of the primary ions that is caused by the parallel inductive electric field in tokamaks and valid in all collisionality regimes is derived via the Hirshman-Sigmar moment approach. Also the expression of the collisional impurity ions poloidal rotation velocity that is caused by the parallel inductive electric field in tokamaks is derived. The poloidal rotation velocities of the primary ions and the impurity ions are sensitive to the primary ion collisionality parameter and the impurity strength parameter. The poloidal rotation velocities of the primary ions and the impurity ions decrease with the primary ion collisionality parameter and decrease with the impurity strength parameter.
