In order to study the effect of RMPs on the plasma parameters in the divertor region with high spatial resolution, the strike-points were swept radially across 39 Langmuir divertor probes during a shot. The current-voltage characteristics data were processed using the novel first-derivative technique. This technique allows one to evaluate the plasma potential and the electron energy distribution function (EEDF), or, subsequently, the electron temperatures and densities. It has been found that in the vicinity of the inner and outer strike points of the divertor, that EEDF is bi-Maxwellian, with a low-energy electron Pracoviště Ústav fyziky plazmatu Kontakt Vladimíra Kebza, kebza@ipp.cas.cz, Tel.: 266 052 975 Rok sběru 2016
