Determination of the EEDF by divertor probes in the COMPASS tokamak(IWSSPP2014)
Original language description
Předneseno na: 6th International Workshop and Summer School on Plasma Physics (IWSSPP2014)Kiten,BG,30.06-06.07.2014 This paper reports experimental data obtained on the COMPASS tokamak by Langmuir probes embedded in the divertor tiles.The measured current-voltage (IV) probe characteristics were processed by the recently published first derivative probe technique for precise determination of the plasma potential and the electron energy distribution function(EEDF). Measurements were performed during L-mode hydrogen and deuterium plasmas with toroidal magnetic field BT =1.15 T, plasma current Ip=180 kA and averaged electron density ne = 8*1019 m3. The spatial profile of the electron temperatures shows that in hydrogen plasmas in the vicinity of the innerand outer strike points the EEDF can be approximated by a bi-Maxwellian distribution,with a dominating low-energy electron population (4 - 7 eV) and a minority of higher energy electrons(12 - 25 eV).In the private flux region between
