A magnetron sputtering discharge with a positively biased anode in argon gas is investigated by Langmuir probe diagnostics and by energy-resolved mass spectrometry. The discharge is operated in continuous (direct current) and in pulsed (high power impulse magnetron sputtering, Hi) mode with a Ti target and in Ar gas. Singly-charged Ar.+., Ti.+., and Ar.2..+. and doubly-charged Ar.2+. and Ti.2+. ions are observed. A novel approach is to bias the magnetron anode. Application of a positive anode voltage shifts the kinetic energies of plasma ions by qe.0.V.a., where V.a. is the anode voltage and qe.0. is the ion charge. It allows for an effective control of plasma ion energies.
