The present EU patent (EP3788181A1) resides in the unifying idea of ​​synchronizing a positive voltage pulse supplied to an electrically conductive or ferromagnetic tube and a exciting negative voltage pulse on a hollow cathode induced on the background of a high-frequency capacitive discharge. In one embodiment, the invention relates to a method of generating low-temperature plasma in a vacuum chamber comprising a hollow cathode and an electrode, the method comprising the step of igniting the pulsed DC discharge in the hollow cathode wherein the positive voltage pulse at least partially overlaps with the negative voltage pulse, and the positive voltage pulse at least partially overlaps with the negative voltage pulse on the hollow cathode.
