Abstract: The dynamics of a nanosecond discharge with an extended hollow cathode in argon is studied and the electron energy distribution function (EEDF) in a plasma column is calculated. The issues of the formation of the EEDF in the discharge column and inside the cathode cavity are considered. The conditions of the validity the two-term approximation of the EEDF in the plasma column are analyzed and the appropriate evaluations are given.

Keywords: hollow cathode, pulse discharge, argon, electron energy distribution function.
