On-surface potential and radial electric field variations in electron root stellarator plasmas
J. M. García-Regaña, T. Estrada, I. Calvo +8
In the present work we report recent radial electric field measurements carried out with the Doppler reflectometry system in the TJ-II stellarator. The study focuses on the fact th…
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…
Stellarator impurity flux driven by electric fields tangent to magnetic surfaces
Ivan Calvo, Felix I. Parra, J. L. Velasco +2
The control of impurity accumulation is one of the main challenges for future stellarator fusion reactors. The standard argument to explain this accumulation relies on the, in prin…
Oscillatory relaxation of zonal flows in a multi-species stellarator plasma
E. Sánchez, I. Calvo, J. L. Velasco +5
The low frequency oscillatory relaxation of zonal potential perturbations is studied numerically in the TJ-II stellarator (where it was experimentally detected for the first time).…
