Publications, 19 June 2023

We offer to your attention a preprint “Experimental laser-plasma diode with magnetic insulation for neutron generation” P13-2023-10 issued by the JINR Publishing Department. The authors are E. D. Vovchenko (National Research Nuclear University MEPhI), A. A. Isaev (National Research Nuclear University MEPhI), K. I. Kozlovskiy (National Research Nuclear University MEPhI), K. A. Levterov (VBLHEP), V. N. Shvetsov (FLNP), A. E. Shikanov (National Research Nuclear University MEPhI).

The simulation results of a diode accelerator for generating neutrons using a laser source of deuterons and a system for suppressing electronic conduction by magnetic fields are presented. Options of the formation of an insulating magnetic field by ring permanent magnets and a spiral electrodynamic line are considered. The possibility of realizing an efficient pulsed neutron generator based on such an accelerator is shown. The results obtained in numerical and physical experiments allow one to expect the achievement of record values of the energy cost per one neutron yield using the nuclear reaction T(d,n)4 He.

The study has been carried out at the Frank Laboratory of Neutron Physics JINR.
