Description

We report results of the evaluation of the plasma potential, the electron temperature and the electron density during the current shots in the COMPASS tokamak, (IPP.CR, Prague, Czech Republic). The comparisons with results from model calculations based on an extended formula for the electron probe current show a satisfactory agreement. The results presented demonstrate that the procedure proposed allows one to acquire additional plasma parameters using the electron part of the current-voltage Langmuire probe (LP) characteristics in tokamak edge plasma probe measurements.
