Plasma Parameters on COMPASS Divertor during Ohmic D-Shaped Plasmas(IWEP2013)

Popis výsledku v původním jazyce

Předneseno na konf.:International Workshop on Electric Probes in Magnetized Plasmas,Madrid,09.-12.07.2013 This paper reports on probe measurements of the electron energy distribution function and plasma potential in the divertor region of the COMPASS tokamak during D-shaped plasmas.The probe data have been processed using the novel first-derivative technique.A comparison with the results obtained by processing the same data with the classical probe technique,which assumes Maxwellian electron energy distribution functions is presented and discussed.In the vicinity of the inner and outer strike points of the divertor the electron energy distribution function is found to be bi-Maxwellian, with a dominating low-energy electron population (4-7eV) and a minority of higher energy electrons (10-20 eV).In the private flux region between the two strike points the electron energy distribution function is found to be Maxwellian with temperatures in the range of 7-10 eV.The comparative analysis
