Determination of the Electron Energy Distribution Function in the ISTTOK Tokamak (VEIT2013)
Original language description
Předneseno na:International Summer School on Vacuum, Electron and Ion Technologies,Sozopol,07.-11.10.2013 The first derivative probe technique was applied to study the ISTTOK tokamak edge plasma.This technique employs the electron part of the Langmuir probe current-voltage (IV) characteristic and yields information on the plasma potential and the electron energy distribution function (EEDF).The IV characteristic was measured with new electrical probes mounted on a horizontal manipulator,one oriented inparallel and the other perpendicularly to the magnetic field lines.Using the first-derivative probe technique, the plasma potential and the EEDF at different radial positions were acquired.We show that,in the edge plasma, the EEDF is non-Maxwellian and can be approximated by a bi-Maxwellian one with a dominant cold electron population and a minority group of hot electrons.In the Scrape-Off-Layer,the EEDF obtained is Maxwellian. The comparison of the plasma parameters evaluated using
