The invention relates to a method for the repeatable initiation of propellent charges in a weapon system, for example in the firing of projectiles from a barrel weapon, through electrical discharge between a rear electrode (22) and a front electrode (21) in a combustion chamber channel (3) filled with filler gas and comprising a combustion chamber combustion element (30), in which the filler gas in the combustion chamber channel (3) is ionized via a high-voltage potential from at least one ionizing electrode (100, 101, 102, 103), which ionization increases the electrical conductivity in the combustion chamber channel (3) so that an electrical flashover, through electrical discharge via a high-voltage generator (5) between the rear electrode (22) and the front electrode (21), is generated from the rear electrode (22) via at least one ionizing electrode (100, 101, 102, 103) onward to the front electrode (21), which results in hot ignition gas with plasma-like state being expelled from the combustion chamber channel (3). The invention also relates to a plasma generator for the said method, and to an ammunition unit comprising the said plasma generator.
