Evaluation Of the Scrape-off-Layer Plasma Parameters by Horizontal Reciprocating Langmuir Probe in the COMPASS Tokamak(VEIT2013)

Popis výsledku v původním jazyce

Předneseno na:International Summer School on Vacuum, Electron and Ion Technologies,Sozopol, 07.-11.10.2013 The Scrape-Off-Layer (SOL) parameters in the COMPASS tokamak are studied by using a Langmuir probe mounted on the horizontal reciprocating manipulator. The radial profiles of the plasma potential, the electron energy distribution function and the electron densities are derived from the measured current-voltage probe characteristics by applying the first derivative probe technique. It has been shownthat close to the tokamak wall the electron energy distribution function is Maxwellian, while in SOL, in the vicinity of the last closed flux surface and inside the confined plasma the electron energy distribution function is bi-Maxwellian with a low energy electron fraction dominating over the higher energy one. The radial profiles of the electron pressure and the parallel electron power flux density in COMPASS are also presented.
