The use of the Biorthogonal Decomposition for the identification of zonal flows at TJ-II
B. Ph. van Milligen, E. Sánchez, A. Alonso +4
This work addresses the identification of zonal flows in fusion plasmas. Zonal flows are large scale phenomena, hence multipoint measurements taken at remote locations are required…
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…
Parallel and perpendicular turbulence correlation length in the TJ-II Stellarator
B. Ph. van Milligen, A. Lopez Fraguas, M. A. Pedrosa +3
Long range correlations were measured using two remote reciprocating Langmuir probe systems at TJ-II. The influence of the rotational transform on the correlation was studied by sc…
Dynamics of zonal flow-like structures in the edge of the TJ-II stellarator
J. A. Alonso, J. L. Velasco, J. Arévalo +4
The dynamics of fluctuating electric field structures in the edge of the TJ-II stellarator, that display zonal flow-like traits, is studied. These structures have been shown to be…
Dynamic transport regulation by zonal flow-like structures in the TJ-II stellarator
J. A. Alonso, C. Hidalgo, M. A. Pedrosa +3
Floating potential structures that are correlated over a long distance are observed with a 2D probe array in the plasma edge of the TJ-II stellarator. We introduce a method based o…
Zonal flows and long-distance correlations during the formation of the edge shear layer in the TJ-II stellarator
Ivan Calvo, Benjamin A. Carreras, Luis Garcia +2
A theoretical interpretation is given for the observed long-distance correlations in potential fluctuations in TJ-II. The value of the correlation increases above the critical poin…
