The injection of heavy ions such as Mg+ or Ca+ into a tokamak such that they are trapped in “fat” banana orbits is proposed as a technique for creation of a radial electric field. Such a field is of interest for improving the confinement of fuel ions relative to the confinement of alpha-particle ash.
