A feasibility study for a Doppler Reflectometer System in the JT-60SA tokamak
D. Carralero, T. Happel, T. Estrada +5
In this work we present a study on the viability and practicality of installing a Doppler reflectometer (DR) system in the JT-60SA advanced tokamak. First, we discuss its scientifi…
H-mode transition in the TJ-II stellarator plasmas
T. Estrada, C. Hidalgo
Since the first H-mode transitions were observed in TJ-II plasmas in 2008, an extensive experimental effort has been done aiming a better physics understanding of confinement trans…
Impact of magnetic islands on plasma flow and turbulence in W7-X
T. Estrada, E. Maragkoudakis, D. Carralero +13
The effect of magnetic islands on plasma flow and turbulence has been experimentally investigated in the stellarator W7-X. Magnetic configurations with the 5/5 magnetic island posi…
Radial electric field and density fluctuations measured by Doppler reflectometry during the post-pellet enhanced confinement phase in W7-X
T. Estrada, D. Carralero, T. Windisch +13
Radial profiles of density fluctuations and radial electric field, , have been measured using Doppler reflectometry during the post-pellet enhanced confinement phase achieved,…
