Book Description
The edge fluctuations play a critical role in the overall tokamak confinement. Experiments on TEXT show that electrostatic fluctuations in the edge plasma are the dominant mechanism for energy and particle transport. The basic mechanisms responsible for the edge turbulence are the subject of ongoing research in fusion devices. To understand the driving forces responsible for edge fluctuations, a novel experiment is underway on TEXT to actively modify the turbulence at the plasma edge by launching waves using electrostatic probes in the shadow of the limiter. This technique permits active probing of the spectral properties of the edge turbulence. This new approach to the study of edge fluctuations can provide more insight into the basic dynamics of the turbulence and may, in turn, enable detailed comparison with the theory. These experiments, which rely on the use of oscillating electric fields at the plasma edge, complement edge fluctuation control studies that are presently limited to the use of applied dc biasing to influence the edge electric field profile. These experiments have been extended to control of the edge plasma fluctuation level, using feedback to explore its effects on the edge turbulence characteristics as well as on confinement.

Experimental Study of the Edge Plasma of the Tore Supra Tokamak
Author: Martin Kubic
Publisher: LAP Lambert Academic Publishing
ISBN: 9783847328711
Category :
Languages : en
Pages : 68
Book Description
The study of edge plasma physics in tokamaks has developed rapidly in recent years and is now considered as one of the major research areas of magnetic fusion. Edge probe techniques are a necessary experimental contribution to such studies, providing information about the plasma flux to the walls of the reactor. The experiments that were carried out on the Tore Supra tokamak to investigate the scrape-off layer conditions in presence of multiple discrete limiters are presented. The baseline of the scenario is to limit the discharge on discrete limiters on the low field side of the tokamak chamber, increasing the minor radius while the safety factor is kept at a constant value 4.8. Analytical tools for 3D magnetic connection analysis and magnetic field mapping together with a new method for LCFS evaluation are also presented."
