The regime of operation of an explosive-emission diode is affected by a matching transformer between this diode and a double forming line of a high-current electron accelerator. Preliminary forced demagnetization of the transformer core makes the shape of the voltage pulse applied to the cathode close to the optimum, corresponding to a decrease in the resistance of the anode-cathode gap related to expansion of the explosive-emission plasma. In addition, matching of the double forming line to the explosive-emission diode significantly decreases the amplitude of parasitic prepulses and increases (to 90-92%) the fraction of energy supplied to the diode during the main current pulse.
