ELECTRON ENERGY DISTRIBUION FUNCTION IN THE DIVERTOR REGION OF THE COMPASS TOKAMAK(VEIT2015)
Original language description
Předneseno na:19th International Summer School Vacuum, Electron and Ion Technologies, Sozopol,BG, 21-25.09.2015 The plasma parameters during an L-mode hydrogen discharge in the COMPASS tokamak with a toroidal magnetic field BT =1.15 T and a line-averagedelectron density ne = 61019 m3 and with a plasma current variation from 209 kA to 100 kA were studied in the divertor region. It is shown that as the plasma current decreases, the position of the outer strike point changes within a few millimeters. In contrast, the position of the inner strike point is shifted towards the high-field side by about 5 cm. The electron energy distribution function (EEDF) for 209 kA at the high-field side and the private region is Maxwellian with a temperature in the rangeof 5 - 9 eV, while around the outer strike point and the low-field side it is bi-Maxwellian with a low-energy electron group (4 - 5 eV) and higher energy electrons (10 - 20 eV). As the plasma current decreases, the appearance of the
