The possibility of sharpening the rear front of quasi-spark discharge which creates a magnetic field pulse in a pulsed plasmatron with induction discharge excited in a toroidal plasma vortex in semi-open cylindrical chamber on the side wall of which electrically exploding wires are placed, and near the opposite ends – cathode and anode connected to a capacitive storage is considered. The sharpening of rear front is achieved by including electro-explosive current interrupter in anode circuit. The aim of the work is to estimate the duration of trailing edge for quasi-spark discharge when using electro-explosive current interrupter and to calculate the cross section of the conductor used in it, as well as to experimentally verify the results of the calculations.
Key words: :pulsed plasmatron, toroidal plasma vortex, quasi-spark discharge, electro-explosive current interrupter, pulsed magnetic field, induction discharge.
