PULSED NEUTRON ACCELERATION TUBE Russian patent published in 2012 - IPC H05H5/00 

FIELD: physics.

SUBSTANCE: present invention relates to devices for accelerating ions in electrostatic fields, and specifically to equipment for generating neutrons during nuclear interaction of deuterons with tritium targets. The disclosed device has a vacuum-arc source of deuterons, consisting of coaxially arranged annular cathode and anode, saturated with deuterium, separated by an annular insulator, accelerating electrodes, a target saturated with a heavy hydrogen isotope, as well as a magnetic electron lens with a longitudinal magnetic field, lying between the deuteron source and the target. The disclosed device is provided with additional, identical to the above-said, target, accelerating electrodes and magnetic lens, lying on the other side of the deuteron source mirror symmetrically about the deuteron source. Another version is also possible, where the deuteron source has, between the cathode and the anode, an additional annular ignition electrode, separated by annular insulators.

EFFECT: high efficiency of generating neutrons.
