Description	Předneseno na:6th International Workshop and Summer School on Plasma Physics (IWSSPP2014),Kiten,BG,30.06.-06.07.2014, The first derivative probe technique was applied to study the ISTTOK tokamak 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 in parallel 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 vicinity of the last close flux surface (LCFS),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 limiter shadow, the EEDF obtained is Maxwellian.A comparison Předneseno na:6th International Workshop and Summer School on Plasma Physics (IWSSPP2014),Kiten,BG,30.06.-06.07.2014, The first derivative probe technique was applied to study the ISTTOK tokamak plasma.
