Plateau regime dynamics of the relaxation of poloidal rotation in tokamak plasmas

A theory of the relaxation dynamics of the radial electric field toward its neoclassical value in the regime of subsonic poloidal rotation is presented. It is shown that the relaxation occurs via damped oscillations on time scales proportional to the ion transit time.
