Plasma Potential and Electron Energy Distribution Function Measured by Vertical Reciprocating Langmuir Probe in the COMPASS Tokamak Edge Plasma(IWSSPP2012)
Original language description
Předneseno na:5th International Workshop and Summer School on Plasma Physics, Kiten,BG,25.06-30.06.2012, Langmuir probes (LP)allow local measurements of the plasma potential, the charged particles density and the electron energy distribution function (EEDF). The knowledge of the real EEDF is of great importance in understanding the underlying physics of processes occurring at the plasma edge in tokamaks, such as the formation of transport barriers, plasma?wall interactions, and edge plasma turbulence. In magnetized plasma, the electron part of the IV characteristics is distorted due to the influence of the magnetic field. This is why the kinetic theory developed in the non-local approach may be used for the evaluation of the EEDF from the first-derivative of the electron current of the IV characteristics. In this work we present the first results for the evaluation of the EEDFs by using data obtained by a vertical reciprocating probe at the edge plasma area of the COMPASS tokamak
