On the possibility of determining the energy-distribution function of nonlocal penning electrons by measuring the current to wall electrode in afterglow plasma

摘要

The results of numerical simulation of the afterglow plasma of pulsed discharge in a nonlocal regime confirm the possibility of determining the energy-distribution function (EDF) of nonlocal penning electrons by measuring their current to a wall electrode. It is shown that the EDF of nonlocal Penning electrons is proportional to the first derivative of the electron-current density with respect to potential on the wall electrode.
