	Scheme for thermonuclear neutron generation in compact Budker-Post trap with barrel-shaped pulsed magnetic field produced by two symmetrically located thin coils with diameter not exceed 0.05 m is proposed. During neutron generation in the trap simultaneously forms plasma which include hydrogen nuclides with density up to 10¹³ m-3 and two pulsed counter hydrogen nuclides flows accelerated in the diodes. Diodes consist of transparent anode with the form of sphere sector symmetrically covered by the same form grounded cathode. Diodes located symmetrically in front of each other, coaxially to magnetic trap. Computer simulation shows possibility to generate up to 1010 neutrons per pulse for deuterium-tritium compound in the diode system with transverse dimension ~0.1 m, amplitude and accelerating pulse duration 5.105 V and 100 nsec. The value of magnetic induction in the center of the trap should be approximately equal to 20 T.

	This paper presents the new experimental results concerning acceleration of deuterium ions extracted from laser plasma in the rapid-growing nonuniform magnetic field in order to initiate the nuclear reactions D(d, n)3He and Т (d,n)4He. In order to obtain plasma a laser that generates in Q-switched mode the pulses of infrared radiation (λ = 1.06 μm) with the energy W ≤ 0.85 J and duration of ≈10 ns. In the present study, the velocity of a bunch of a laser plasma at a magnetic field induction rate of 3-10⁸ T/s was experimentally measured, and angular distributions of accelerated particle fluxes were measured in the range from 0 to 30 degrees. The maximum and mean ion velocities were determined by the time-of-flight technique. The proposed system allows the generation of neutrons, including possibly thermonuclear ones, on counterflows using two similar magnetic accelerators located coaxially, facing each other. In this case the problem related to degradation of solid neutron-generating targets is resolved. There also occurs a possibility of fast accumulated running time of packed solid targets at using of deuteron-tritium laser targets.

This paper presents the new experimental results concerning acceleration of deuterium ions extracted from laser plasma in the rapid-growing nonuniform magnetic field in order to initiate the nuclear reactions D(d, n)3He and Т (d,n)4He. In order to obtain plasma a laser that generates in Q-switched mode the pulses of infrared radiation (λ = 1.06 μm) with the energy W ≤ 0.85 J and duration of ≈10 ns. In the present study, the velocity of a bunch of a laser plasma at a magnetic field induction rate of 3-10⁸ T/s was experimentally measured, and angular distributions of accelerated particle fluxes were measured in the range from 0 to 30 degrees. The maximum and mean ion velocities were determined by the time-of-flight technique. The proposed system allows the generation of neutrons, including possibly thermonuclear ones, on counterflows using two similar magnetic accelerators located coaxially, facing each other. In this case the problem related to degradation of solid neutron-generating targets is resolved. There also occurs a possibility of fast accumulated running time of packed solid targets at using of deuteron-tritium laser targets.
