Statistical theory of intermittency in a multi-scale model of MHD and micro-turbulence
Johan Anderson, Eun-jin Kim
Traditionally the effects of MHD instabilities and micro-instabilities on plasma confinement are investigated separately. However, these two instabilities often occur simultaneousl…
Zonal flow generation in collisionless trapped electron mode turbulence
J. Anderson, H. Nordman, R. Singh +1
In the present work the generation of zonal flows in collisionless trapped electron mode (TEM) turbulence is studied analytically. A reduced model for TEM turbulence is utilized ba…
Non-perturbative models of intermittency in edge turbulence
Johan Anderson, Eun-jin Kim
A theory of the probability distribution function (PDF) tails of the blob density in plasma edge turbulence is provided. A simplified model of the fast convective radial transport…
The momentum flux probability distribution function for ion-temperature-gradient turbulence
Johan Anderson, Eun-jin Kim
There has been overwhelming evidence that coherent structures play a critical role in determining the overall transport in a variety of systems. We compute the probability distribu…
Quasilinear analysis of the zonal flow back-reaction on ion-temperature-gradient mode turbulence
Johan Anderson, Jiquan Li, Yasuaki Kishimoto +1
There is strong evidence in favor for zonal flow suppression of the Ion-Temperature-Gradient (ITG) mode turbulence, specifically close to the linear stability threshold. The presen…
Effects of parallel ion motion on zonal flow generation in ion-temperature-gradient mode turbulence
J. Anderson, J. Li, Y. Kishimoto
The role of parallel ion motion for zonal flow generation in ion-temperature-gradient (ITG) mode turbulence is investigated with focus on the effects of acoustic modes and toroidic…
