Plasma potential evaluated by Ball pen and Langmuir probes in the COMPASS tokamak

Popis výsledku v původním jazyce

Předneseno na:6th International Workshop and Summer School on Plasma Physics (IWSSPP2014),Kiten,BG,30.06.-06.07.2014, The radial distribution of the main plasma parameters in the scrape-off-layer (SOL) of the COMPASS tokamak is measured during L and H-mode regimes by using both Langmuir and Ball-pen probes mounted on a horizontal reciprocating manipulator. Radial profiles of the plasma potential and the electron energy distribution functions (EEDF), i.e. electron temperatures and densities, are derivedfrom measured Langmuir probe current-voltage characteristics by applying the first derivative probe technique (FDPT) and compared with the results from classical probe technique. Ball-pen probe measurements provides direct evaluation of the plasma potential with high temporal resolution. The derived results for plasma potential from Langmuir probe and Ball-pen probe are in a quantitative agreement.
