Generalized results of investigations of the system of coaxial geometry of electrodes with an internal anode enclosed by a hollow cylindrical cathode are reported at various parameters: the radiation energy of a pulsed yttrium-aluminum garnet laser from 0.1 J to 1 J with a pulse duration of 10 ns and a wavelength of 1.06 mkm, accelerating voltage of a high voltage pulse source according to Arkadiev-Marx scheme from 300 kV to 450 kV. In addition, two methods for suppressing electronic conduction, a constant magnetic field with azimuthal symmetry, and a pulsed magnetic field of a spiral line adjacent to the cathode are considered. It has been experimentally established that the suppression of the electronic conductivity by the field of permanent magnets has a number of significant drawbacks. At a radiation energy of 0.85 J for a laser target, a current of the order of 1 kA with an accelerating voltage of the order of 400 kV was detected in a diode with magnetic insulation. An increase in the laser radiation energy from 0.1 to 0.85 J leads to an increase in the total number of deuterons produced in a laser plasma to about 10¹⁵.
