Abstract
The portion Φ1 of the ambipolar potential Φ which produces an electric field in the flux surfaces of a stellarator is self-consistently calculated, and its effect on stellarator transport at low collisionality is considered. The effect is small in a parameter δh, which is proportional to the square root of the ripple amplitude, εh. However, since δh can be an appreciable fraction of 1 for realistic parameters, the effect of Φ1 on transport can also be appreciable. Whether the effect is harmful or beneficial to confinement depends on the degree of pressure anisotropy and on the sign of p⊥−p∥.
