Measurement of zero-frequency fluctuations generated by coupling between Alfven modes in the JET tokamak
Juan Ruiz Ruiz, Jeronimo Garcia, Michael Barnes +13
We report the first experimental detection of a zero-frequency fluctuation that is pumped by an Alfvèn mode in a magnetically confined plasma. Core-localized bidirectional Alfvèn m…
Electrostatic microturbulence in W7-X: comparison of local gyrokinetic simulations with Doppler reflectometry measurements
A. González-Jerez, J. M. García-Regaña, I. Calvo +5
The first experimental campaigns of Wendelstein 7-X (W7-X) have shown that turbulence plays a decisive role in the performance of neoclassically optimized stellarators. This stress…
Ion temperature and density gradient driven instabilities and turbulence in Wendelstein 7-X close to the stability threshold
L. Podavini, A. Zocco, J. M. García-Regaña +4
Electrostatic gyrokinetic instabilities and turbulence in the Wendelstein 7-X stellarator are studied. Particular attention is paid to the ion-temperature-gradient (ITG) instabilit…
Phase-space entropy cascade and irreversibility of stochastic heating in nearly collisionless plasma turbulence
Michael L. Nastac, Robert J. Ewart, Wrick Sengupta +3
We consider a nearly collisionless plasma consisting of a species of `test particles' in 1D-1V, stirred by an externally imposed stochastic electric field. The mean effect on the p…
