- ПубликацияТолько метаданныеThe Effect of the Polarity and Design of the Discharge System on the X-ray Spectrum of the Micropinch Discharge Plasma(2019) Bashutin, O. A.; Grigoryeva, I. G.; Kostyushin, V. A.; Savelov, A. S.; Salakhutdinov, G. K.; Башутин, Олег Алексеевич; Григорьева, Ирина Гаяровна; Савёлов, Александр Сергеевич; Салахутдинов, Гаяр Харисович© 2019, Pleiades Publishing, Ltd.The spectral composition and X-ray radiation yield of a micropinch discharge plasma obtained at a facility of the low-inductance vacuum spark type are studied as a function of the polarity and design of the electrodes of the discharge system. It is shown that the X-ray radiation of the micropinch discharge plasma depends on the configuration of the electric field in the interval between the discharge electrodes, which determines the amount of erosion products involved in the micropinch process, resulting in the increase in the plasma density and its radiative characteristics.
- ПубликацияТолько метаданныеThe Formation of Microstructures on a Steel Surface under a Plasma-Focus Discharge(2022) Kirko, D. L.; Sidorov, P. P.; Bashutin, O. A.; Savelov, A. S.; Кирко, Дмитрий Леонидович; Сидоров, Павел Павлович; Башутин, Олег Алексеевич; Савёлов, Александр СергеевичAbstract: The surface of metals after irradiation by intense flows of an argon plasma arising in a plasma focus has been studied. Steel, copper, tungsten, and molybdenum samples have been examined. Microstructures of different types have been detected. It has been found that the steel sample surfaces contain micropores 0.1‒3 μm in size with a shape close to round. On the copper and tungsten plate sample surfaces, the occurrence of finely dispersed structures 0.5‒20 μm in size has been observed. Possible mechanisms of the formation of these microstructures are discussed. © 2022, Pleiades Publishing, Ltd.
- ПубликацияТолько метаданныеMeasurement of Electron Emission Spectra from Micropinch Discharge Plasma(2020) Bashutin, O. A.; Grigoryeva, I. G.; Korf, A. N.; Savelov, A. S.; Salakhutdinov, G. K.; Башутин, Олег Алексеевич; Григорьева, Ирина Гаяровна; Корф, Александр Николаевич; Савёлов, Александр Сергеевич; Салахутдинов, Гаяр Харисович© 2020, Pleiades Publishing, Ltd.Abstract: In this paper, we describe a small-size magnetic spectrometer of electrons that allowed studying the spectral composition of electron emission in the energy range of 5–400 keV from a micropinch discharge plasma using a low-inductance vacuum spark setup.
- ПубликацияТолько метаданныеStudy of the Spectral Composition of X-ray Emission from Different Regions of Micropinch Discharge Plasma(2019) Balovnev, A. V.; Bashutin, O. A.; Grigoryeva, I. G.; Salakhutdinov, G. Kh.; Башутин, Олег Алексеевич; Григорьева, Ирина Гаяровна; Салахутдинов, Гаяр ХарисовичThe measurement technique and results are presented from studies of the spectral composition of X-ray emission from different regions of micropinch discharge plasma in a low-inductive vacuum spark device. X-ray spectra are measured in the photon energy range of 1-30 keV for the radiation emerging from the plasma spot, near-anode plasma, and anode regions of the micropinch discharge plasma. It is experimentally established that, in the energy range under study, the intensity of X-ray emission from the plasma spot exceeds that from the near-anode and anode regions.
- ПубликацияТолько метаданныеCharacteristics of X-ray Emission from a Micropinch Discharge at Different Polarities of the Discharge Electrodes(2019) Balovnev, A. V.; Bashutin, O. A.; Grigoryeva, I. G.; Manokhin, I. L.; Salakhutdinov, G. Kh.; Башутин, Олег Алексеевич; Григорьева, Ирина Гаяровна; Салахутдинов, Гаяр ХарисовичThe measurement technique and results are presented from studies of the X-ray spectra and X-ray yield from micropinch discharge plasma in a low-inductive vacuum spark device at different polarities of the discharge electrodes. The measurements were performed using the specially designed diagnostic system based on thermoluminescent and scintillation detectors. This made it possible to perform measurements in the photon energy range of 1-300 keV.
- ПубликацияТолько метаданныеMethods for Research on the Spectra of Pulse X-Ray Radiation and Emission of Micropinched Plasma Electrons(2020) Bashutin, O. A.; Grigoryeva, I. G.; Korf, A. N.; Salakhutdinov, G. K.; Башутин, Олег Алексеевич; Григорьева, Ирина Гаяровна; Корф, Александр Николаевич; Салахутдинов, Гаяр Харисович© 2020, Pleiades Publishing, Ltd.Abstract—The results of experimental studies are presented on the spectral composition of pulsed X-ray radiation and electron emission of a micropinch plasma in a wide 1–300 keV energy range. Studies were conducted on a “low inductive vacuum spark” apparatus at various discharge currents. The results we obtained make it possible to determine the effect of the discharge current on the spectral composition of X-ray radiation and the electron emission of a micropinch plasma.
