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…
Particle transport after pellet injection in the TJ-II stellarator
J. L. Velasco, K. J. McCarthy, N. Panadero +17
We study radial particle transport in stellarator plasmas using cryogenic pellet injection. By means of perturbative experiments, we estimate the experimental particle flux and com…
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…
Investigation of the specific plasma potential oscillations with geodesic acoustic mode frequencies by heavy ion beam probing
A. V. Melnikov, L. G. Eliseev, A. V. Gudozhnik +6
Investigation of the specific oscillations with frequencies 15-30 kHz on the T-10 tokamak (R= 150cm, a = 30 cm) with Heavy Ion Beam Probe (HIBP) diagnostic was conducted in regimes…
