    PLASMA PARAMETERS IN DIVERTOR REGION OF THE COMPASS TOKAMAK DURING ISOTOPE EFFECT EXPERIMENT (IWSSPP 2016)

  • Original language description

    Předneseno na:n7th International Workshop and Summer School on Plasma Physics (IWSSPP 2016), Kiten,26.06.-02.07.2016,nEven though there is a large experimental evidence that isotopic composition has an impact on confinement properties of the tokamak plasma, the main mechanism governing the isotope effect is still unclear. In order to study the effect of isotopes in L-mode, Langmuir probe measurements of the plasma parameters were performed in the divertor region of the COMPASS tokamak. The probe data has been processed using two different methods the first-derivative probe technique (FDPT) for evaluating the real electron energy distribution function (EEDF) and the classical method that assumes Maxwellian EEDF. The measurements were done in hydrogen and deuterium, their mixtures as well as in hydrogen-helium mixture. The influence of glow discharge cleaning of the tokamak chamber with He, H2 or D2 on plasma parameters was also studied. It was found that the EEDF in the divertor region is bi-Maxwellian with a low-energy electron population with temperatures 4-6 eV and high energy electron group 10-25 eV. However, during some shots the EEDF is bi-Maxwellian only at the beginning and changes to Maxwellian with the time. n
