Numerical simulation of the treatment of probe current-voltage characteristics under conditions of anisotropic velocity distribution of electrons

The results are given of numerical experiment in processing the current-voltage characteristics of a plane probe in a plasma with an anisotropic function of velocity distribution of electrons (EVDF). In order to find the first and second moments of EVDF expansion in Legendre polynomials, the known procedures are employed to develop and approve the computer codes for numerical reconstruction of these moments by the measured first derivatives of electron current to the probe for different orientations of the latter.
