    Formation of convective cells during scrape-off layer biasing in the CASTOR tokamak

  • Original language description

    We describe experiments with a biased electrode inserted into the scrape-off layer (SOL) of the CASTOR tokamak. The resulting radial and poloidal electric field and plasma density modification are measured by means of Langmuir probe arrays with high temporal and spatial resolutions. Poloidally and radially localized stationary structures of the electric field (convective cells) are identified and a related significant modification of the particle transport in the SOL is observed.

    Vytváření vodivých buněk během polarizace okrajového plazmatu tokamaku CASTOR

  • Czech description

    Polarizace okrajového plazmatu tokamaku CASTOR byla prováděna pomocí masivní grafitové elektrody umístěné v okrajové oblasti plazmatu a nabíjené na kladný potenciál. Vznikající elektrické pole v radiálním a poloidálním směru způsobuje změny hustoty plazmatu na daných magnetických površích a vznik tzv. vodivých buněk.
