Abstract
The plasma is formed between electrodes to be energized from an electric power source, containing a partially ionized mass having a luminescence region including neutral atoms (NA), primary electrons (PE), secondary electrons (SE), and ions. The method comprises the steps of: accelerating the primary electrons (PE) toward one of said electrodes polarized by a positive high voltage pulse impacting primary electrons (PE) against said electrode and ejecting secondary electrons (SE) from it; subsequently, accelerating the secondary electrons (SE) toward the luminescence region by polarization of said electrode by a negative voltage to collide the secondary electrons with neutral atoms (NA) and producing positive ions (PI) and derived electrons (DE); repeating the previous steps in order to obtain a steady state plasma with a desired degree of ionization.
