ELM transport in the JET scrape-off layer

Analysis of ELM heat pulse propagation in the JET scrape-off layer with an integrated fluid-kinetic approach

Convective transport in the scrape-off layer of tokamaks

A detailed study of blob formation, dynamics, and the associated convective transport in the scrape-off layer sSOLd of tokamak plasmas is presented. Dissipation level in the system, in addition to the blob size, is shown to play an important role in determining whether a blob propagates as a coherent object. Nonlinear SOL interchange/ballooning modes are shown to be capable of creating blobs ne...

Intermittent fluctuations in the TCV scrape-off layer

Probe measurements in the scrape-off layer of tokamak plasmas show that the ion saturation current signal is dominated by large amplitude bursts. Analysis of data time series from tokamak á configuration variable of unprecedented duration reveals that both burst amplitudes and waiting times are exponentially distributed. The average burst wave form has an exponential shape with a characteristic...

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...
