Numerical approach to the parallel gradient operator in tokamak scrape-off layer turbulence simulations and application to the GBS code

This paper presents two discretisation schemes for the parallel gradient operator used in scrape-off layer plasma turbulence simulations. First, a simple model describing the propagation of electrostatic shearAlfvén waves, and retaining the key elements of the parallel dynamics, is used to test the accuracy of the different schemes against analytical predictions. Themost promising scheme is the...

The Scrape - Off - Layer in Alcator C - Mod – Transport , Turbulence , and Flows

Research on the scrape-off-layer plasma of the Alcator C-Mod Tokamak is reviewed. The research has focused on understanding the transport of energy and particles both parallel and perpendicular to the magnetic field. Large differences between the inboard, high-field side scrape-off-layer and the outboard, low-field side are found. On the outboard side large levels of anomalous cross-field trans...

Aspect ratio effects on limited scrape-off layer plasma turbulence

Convective transport suppression in the scrape-off layer using ion cyclotron resonance heating on the ASDEX Upgrade Tokamak.

Turbulence properties in the scrape-off layer (SOL) in the presence of ion cyclotron frequency heating (ICRH) are compared to instances where it is absent. The discharges are all in a high-confinement mode (H-mode) regime. During ICRH, the SOL plasma density increases whereas turbulence large-scale and convective structures are shown to be suppressed. The probability distribution function is th...
