Abstract
It is generally accepted that during argon plasma decay at atmospheric pressure, the disappearance of charged particles is brought about by electron-ion recombination. For a temperature of about 1 eV, recombination is partially counterbalanced by ionization. When the plasma is confined the electron losses through ambipolar diffusion are not negligible. The aim of this communication is to show the relative influence of the various processes by comparing the experimental results with theoretical estimations.
