Effect of the Resonant Magnetic Perturbation on the Plasma Parameters in Divertor Region of the COMPASS Tokamak (IWEP2015)
Original language description
Předneseno na:11th International Workshop on Electric Probes in Magnetized Plasmas (IWEP),Sozopol, BG, 16-19.09.2015, This work discusses the application of Resonant Magnetic Perturbations (RMPs) in the COMPASS tokamak in Ohmic D-shaped discharges, withtoroidal magnetic field BT = 1.15 T, plasma current Ip = 170 kA and line-average electron density ne = 51019 m3. 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
