Properties of Filamentary Structures in Different Regimes of Plasma Confinement on the COMPASS Tokamak
2014
Abstract
A complex electrostatic-magnetic probe diagnostic, called U-probe, has been installed on the tokamak COMPASS recently. Probe composes of two identical towers.
Each tower houses radialy separated 3 sets of 3D coils, a triple probe and a rake of six single Langmuir probes. We present measurements of electric and magnetic properties of the filamentary structures in the scrape off layer plasmas during different regimes of plasma confinement on COMPASS tokamak.
