Langmuir Probe Evaluation of the Plasma Potential in Tokamak Edge Plasma at non-Maxwellian EEDF(IWEP2013)

Popis výsledku v původním jazyce

Předneseno na International Workshop on Electric Probes in Magnetized Plasmas,Madrid,09.-12.07.2013 In magnetized plasma,the interpretation of the electron part of the current-voltage (IV) characteristics above the floating potential,still remains difficult because it is distorted due to the influence of the magnetic field.For this reason,in the strongly magnetized tokamak plasmas,the ion saturation branch of the IV and the part around the floating potential are usually used when retrieving the plasma parameters.This classical technique only assumes a Maxwellian EEDF, but in fact does not measure the real one.In tokamaks, the assumption for a Maxwellian EEDF is generally valid. However,it exists experimental evidences suggesting non-Maxwellian distributions in tokamak edge plasmas.Recently a new,first derivative probe techniques developed on the base of kinetic theory in non-local approach,was proposed for precise evaluation of the main plasma parameters.This techniques allow to
