Electrostatic potential variations on stellarator magnetic surfaces in low collisionality regimes
Ivan Calvo, J. L. Velasco, Felix I. Parra +2
The component of the neoclassical electrostatic potential that is non-constant on the magnetic surface, that we denote by , can affect radial transport of highly charged i…

Parallel impurity dynamics in the TJ-II stellarator
J A Alonso, J L Velasco, I Calvo +12
We review in a tutorial fashion some of the causes of impurity density variations along field lines and radial impurity transport in the moment approach framework. An explicit and…
