    Energy Efficiency Enhancement of Ionic Diode for Neutron Generation with Electronic Conduction Suppression by the Field of a Permanent Magnet
    (2019) Vovchenko, E. D.; Kozlovskii, K. I.; Lisovskii, M. I.; Rashchikov, V. I.; Shikanov, A. E.; Shatokhin, V. L.; Вовченко, Евгений Дмитриевич; Козловский, Константин Иванович; Ращиков, Владимир Иванович; Шиканов, Александр Евгеньевич; Шатохин, Вадим Леонидович
    © 2019, Springer Science+Business Media, LLC, part of Springer Nature.In order to use neutron generators in applied research, it is important to increase the energy efficiency of neutron generation. For high accelerating voltages, diodes with magnetic insulation are used to suppress electron emission from the cathode in neutron accelerator tubes. A mathematical model describing the dynamics of charged particles in the axial diode with insulation of electrons by the field of a permanent magnet is studied. The model is used to perform a computer experiment that shows a reduction of insulation near the ends of the magnet, which permits up to 40% of the electrons from the cathode to reach the anode of the accelerator tube. An option for making the magnetic insulation more efficient by adding into the magnetic system diaphragms placed in the end zones of a cylindrical cathode is proposed and studied.

    Model of Laser Plasma Acceleration in the Fields of a Spiral Electrodynamic Line
    (2019) Shikanov, A. E.; Vovchenko, E. D.; Kozlovskij, K. I.; Shatokhin, V. L.; Шиканов, Александр Евгеньевич; Вовченко, Евгений Дмитриевич; Козловский, Константин Иванович; Шатохин, Вадим Леонидович
    The acceleration of a plasmoid, for the formation of which a conical spiral expanding in the direction of the expected plasma acceleration is used, in a rapidly increasing magnetic field of complex geometry has been considered. An algorithm for calculating the longitudinal magnetic field in the approximation of replacing a spiral line with a system of rings of variable radius has been presented. A mathematical model that is based on the interaction of the plasmoid magnetic moment with gradient of the longitudinal magnetic field decay has been proposed to analyze the efficiency of the acceleration. The possibility of deuterons reaching an average speed exceeding 10(6) m/s has been shown.

    Improving the efficiency of suppression of electron conductivity in the vacuum accelerator neutron tubes with coaxial diode system
    (2019) Vovchenko, E. D.; Kozlovskii, K. I.; Lisovskii, M. I.; Rashchikov, V. I.; Shikanov, A. E.; Shatokhin, V. L.; Вовченко, Евгений Дмитриевич; Козловский, Константин Иванович; Ращиков, Владимир Иванович; Шиканов, Александр Евгеньевич; Шатохин, Вадим Леонидович
    © Published under licence by IOP Publishing Ltd.Discussed two options for increasing the magnetic isolation efficiency of the electron component in a vacuum neutron tube with coaxial geometry for the acceleration of deuterons. Computer analysis of the previously developed diode systems with magnetic insulation has shown that the suppression ratio does not exceed 50%. The proposed new options of suppression systems used the current ring and diaphragm, located near the edge of the cylindrical anode. Computer analysis showed that for these acceleration geometries the suppression factor could exceed 97%.
