Evaluation of Plasma Potential and Electron Energy Distribution Function by Langmuir Probes in Magnetized Plasma
Original language description
In the strongly magnetized tokamak plasmas the ion saturation branch of the IV and the part around the floating potential are usually used when retrieving the plasma parameters. This method only assumes a Maxwellian EDF for the electrons but in fact doesnot measure the real one. However, some experimental evidences of non-Maxwellian distributions in tokamak edge plasmas are confirmed. The knowledge of the real EEDF is of great importance to understand the underlying physics of processes occurring at the plasma edge in tokamaks, such as the formation of transport barriers, plasma?wall interactions, edge plasma turbulence, etc. In this work the recently publish first derivative probe method for evaluation of the electron energy distribution function based on the kinetic theory in non-local approach is reviewed and results from measurements with vertical reciprocating probe in tokamak COMPASS, Prague, IPP, CR are presented.
