A stable mode of a gasless (vacuum) magnetron discharge with a cold planar cathode-target at a residual pressure as low as 4· 10-3 Pa and a discharge current of 8-12 A (120-200 mA/cm2) is realized. The results of studies of mass-to-charge ion composition are presented, as well as a comparison of main discharge parameters and a deposition rate in gaseous and vacuum modes. Keywords: magnetron, vacuum regime, ion composition, deposition rate.
