Resumo

The experiments were carried out to characterize plasma of a non-sputtering millisecond discharge in hydrogen at a pressure of ~ 1 Torr, pulse duration and a maximum impulse power near 1 ms and 80 kW, correspondingly. It has been demonstrated that the implementation of impulse non-sputtering modes of a magnetron discharge in light gases enables generation of dense non-constricted plasma with no lines of cathode or anode material present in its optical emission spectra.
