Observation of oscillatory radial electric field relaxation in a helical plasma
J. A. Alonso, E. Sanchez, I. Calvo +13
Measurements of the relaxation of a zonal electrostatic potential perturbation in a non-axisymmetric magnetically confined plasma are presented. A sudden perturbation of the plasma…
Electrostatic potential variation on the flux surface and its impact on impurity transport
J. M. García-Regaña, C. D. Beidler, Y. Turkin +5
The particle transport of impurities in magnetically confined plasmas under some conditions does not find, neither quantitatively nor qualitatively, a satisfactory theory-based exp…
Electrostatic potential variations along flux surfaces in stellarators
M. A. Pedrosa, J. A. Alonso, J. M. García-Regaña +6
First observations of electrostatic potential variations within the flux surfaces of a toroidal magnetic confinement device are presented. Measurements are taken in the TJ-II stell…
Compressible impurity flow in the TJ-II stellarator
J Arévalo, J A Alonso, K J McCarthy +3
Fully-ionised carbon impurity flow is studied in ion-root, neutral beam heated plasmas by means of Charge Exchange Recombination Spectroscopy (CXRS) in the TJ-II stellarator. Perpe…
Damping of radial electric field fluctuations in the TJ-II stellarator
J L Velasco, J A Alonso, I Calvo +8
The drift kinetic equation is solved for low density TJ-II plasmas employing slowly varying, time-dependent profiles. This allows to simulate density ramp-up experiments and to des…
Incompressibility of Impurity Flows in Low Density TJ-II Plasmas and Comparison with Neoclassical Theory
J Arévalo, J A Alonso, K J McCarthy +1
Poloidal and toroidal velocities of fully-ionised carbon are measured by means of charge exchange recombination spectroscopy (CXRS) in the TJ-II stellarator. We present a detailed…
