The currents with such parameters can be achieved with the use of super-power disk explosive magnetic generators and a two-stage current pulse sharpening system based on foil electrically exploded current opening switches in a form of a serpentine. The implementation of the explosive current source with a rise time of 100 ns is advisable to be carried out in stages by increasing the magnitude of current. The results of the first-stage experiments, in which the current with the amplitude of 5 MA was produced on the basis of the helical explosive magnetic generator in the load of 10 nH for the time of 110 ns, are presented.</p>explosive magnetic generatorsthermonuclear ignitionelectrically exploded current opening switchinductive loadвзрывомагнитный генератортермоядерное зажиганиеэлектровзрывной размыкатель токаиндуктивная нагрузка[Vesey R.A., Herrmann M.C., Lemke R.W., et al.// Physics of Plasmas. 2007.
