Theiler C Furno I Loizu J Fasoli A 2012 Blob control by creating convective cells using biased electrodes is demonstrated in simple magnetized toroidal plasmas. A two-dimensional array of electrodes is installed on a metal limiter to obtain different biasing schemes. Detailed two-dimensional measurements across the magnetic field reveal the formation of a convective cell, which shows a high degree of uniformity along the magnetic field. Depending on the biasing scheme, radial and vertical blob velocities can be varied significantly. A high level of cross-field currents limits the achievable potential variations to values well below the applied bias voltage. Furthermore, the strongest potential variations are not induced along the biased flux tube, but at a position shifted in the direction of plasma flows. application/pdf https://sonar.ch/global/documents/176725 eng info:eu-repo/semantics/altIdentifier/doi/10.1103/PhysRevLett.108.065005 info:eu-repo/semantics/altIdentifier/pmid/22401080 info:eu-repo/semantics/openAccess Physical review letters. - 2012 Convective cells and blob control in a simple magnetized plasma. http://purl.org/coar/resource_type/c_6501
