Langmuir Probe Measurements of Electron Energy Distribution Function in Magnetized Plasma(IWSSPP2012)
Original language description
Předneseno na konf.: 5th International Workshop and Summer School on Plasma Physics(IWSSPP),Kiten,BG,25.06.-30.06.2012:Incorrect applications of electric probes are commonly found in the literature. The errors mainly arise from a lack of awareness aboutthe multitude of regimes of probe operation and the limits of validity of theories.In this work the methods for using Langmuir probes in magnetized plasmas are reviewed. The electron part of the current-voltage probe characteristic is used in order to obtain the plasma potential and EEDF(respectively electron temperature and electron density).At low values of the magnetic field up to 0.04 T the extended second derivative probe method is used, since in the range 0.04 ? 0.3 T the first derivative method is applied. In high temperature turbulent tokamak edge plasma (magnetic field of 1-2 T) a modified firs derivative method is proposed and used. Comparison of the results obtained with probes perpendicular and parallel to the magnetic field
