Determination of the edge plasma parameters by divertor probes in the COMPASS tokamak(IWSSPP2012)

Popis výsledku v původním jazyce

Předneseno na: 5th International Workshop and Summer School on Plasma Physics,Kiten, BG,25.06-30.06.2012, In magnetized plasma, the interpretation of the electron part of the current-voltage (IV) characteristics above the floating potential still remainsdifficult because the electron part of the IV characteristics is significantly distorted due to the influence of the magnetic field. We recently published results of applying the first-derivative method to process the electron branch of the IV characteristics measured in tokamak edge plasma by Langmuir probes (LPs) to evaluate precisely the plasma potential and the electron energy distribution function (EEDF). In this paper we report experimental data obtained on the COMPASS tokamak by LPs embedded inthe divertor tiles and processed using the first-derivative probe method. The measurements of the current-voltage characteristics in the tokamak divertor area were performed by a newly developed Langmuir probe system.
