New experimental results of obtaining accelerated deuterons in the small-sized diode with magnetic insulation are reported. The effective mode of ion acceleration to energies at 300 keV in the diode with a high voltage anode in order to initiate nuclear reactions D(d, n)3He is obtained with diode current ~0,5 kA and impulse duration ~1 mks in vacuum ~5*10-2 Pa. Containing deuterons laser plasma was generated at the anode during TiD target laser irradiation with a wavelength of 1.06 microns and a power density of ~5*1014 W/m2. Accelerating voltage impulse was formed using Arkadyev–Marx 20 cascade impulse voltage generator with air insulation. Diode cathode covers the anode symmetrically. It is a hollow cylinder permanent magnet with induction on the axis ~0,4 T. Magnetic insulation in accelerating gap leads to suppression of the accelerated electrons current at level of 0.5 in relation to the total diode current. Used methods of accelerating diode ion current, accelerating impulse voltage and penetrating radiations characteristics measurements are described.
