(2019) Vovchenko, E. D.; Kozlovskij, K. I.; Shikanov, A. E.; Karimov, A. R.; Isaev, A. A.; Plekhanov, A. A.; Deryabochkin, O. V.; Вовченко, Евгений Дмитриевич; Козловский, Константин Иванович; Шиканов, Александр Евгеньевич; Каримов, Александр Рашатович; Плеханов, Андрей Александрович; Дерябочкин, Олег Владимирович
© 2019, Pleiades Publishing, Ltd.The collective acceleration of laser plasma ions in a magnetic field generated by a powerful fast-growing current pulse in a low-inductive conical spiral is studied. The velocity of ions for a number of elements which significantly differ in atomic weight are obtained on the basis of collector measurements. The maximum velocity of both light (lithium) and heavy (lead) ions exceed the value of 108 cm/s; for ions of lead, the corresponding energy amounts to a value of ∼1 MeV. A mathematical model of ion acceleration is proposed and simulation results are compared with the experiment.

(2019) Ilyinsky, A. V.; Kutuzov, E. M.; Shikanov, E. A.; Bogdanovich, B. Y.; Nestorovich, A. V.; Senyukov, V. A.; Shikanov, A. E.; Богданович, Борис Юрьевич; Нестерович, Александр Владимирович; Сенюков, Виктор Алексеевич; Шиканов, Александр Евгеньевич
© 2019, Neftyanoe Khozyaistvo. All rights reserved.A method is proposed for remote detection of leaks of productive hydrocarbons from underground main pipelines. The method involves impact on the soil adjacent to the tubing route by the acoustic field of the ultrasonic wave, at which its intensive degassing takes place accompanied by gas evolution from the surface of the earth. In parallel with the process of exposure, a chromatographic analysis of the composition of the released gas is carried out. It is described a device that realizes this method of detecting leaks of productive hydrocarbons associated with local tub damage. The technical solution of the device assumes the presence of an ultrasonic magnetostrictive radiator with power consumption ~ kW and an acoustic waveguide, with which the ultrasonic wave is directed to the earth’s surface. A description is given of an ultrasonic radiator based on a magnetostrictor with a toroidal core, made in the form of an assembly of permangled plates. A small-size chromatograph of a batch production can be used in the apparatus complex. Dimensions and weight of the whole equipment complex allows its placement on a Gazel type vehicle. The results of field tests of the proposed method and the equipment that implements it are given. By their results, one can judge the effectiveness of the proposed method and the hardware complex.

(2019) Shikanov, A. E.; Zhuikov, YuF.; Ilyinskiy, A, V.; Shikanov, E. A.; Шиканов, Александр Евгеньевич
The paper presents the study results of the acoustic effect the oil well bottomhole zone by ultrasonic waves. The formulas allowing to estimate power density of an acoustic wave and its attenuation coefficient are received. Experimentally by three independent neutron logging methods, the acoustic effect effectiveness was shown to increase the bottomhole zone permeability. The experiments were conducted on oil facilities in Tatarstan and Western Siberia. The estimated data on the threshold intensity of the ultrasonic emitter in the well and depth of the effective acoustic impact on the oil reservoir are given.

Acceleration of Macroscopic Clusters in Crossed Magnetic Fields
(2019) Karimov, AlexanderR.; Shikanov, AlexanderE.; Murad, PaulA.; Terekhov, SvyatoslavA.; Каримов, Александр Рашатович; Шиканов, Александр Евгеньевич; Терехов, Святослав Алексеевич
The acceleration of rotating plasma flow in crossed magnetic fields produced momentum transfer between the macroscopic degrees of freedom for a plasma flow was investigated. Results implied a concept for acceleration of plasma flow containing the charged macroscopic particles. Here, the case is treated when the plasma flow consists of electrons, protons, and heavy, multiply charged negative dust particles only. The analysis shows that these charged macroscopic particles have been trapped and, then, accelerated in the main plasma flow. As a result, such complex plasma flow can be accelerated in one axial direction to increase the thrust. It suggests that such complex plasma flow produced, for example, from cosmic dust medium may be used as a propellant and a work body for plasma thrusters.

(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.

(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.
