Институт физико-техничеcких интеллектуальных систем
Институт физико-технических интеллектуальных систем впервые в стране обеспечивает комплексную подготовку специалистов по созданию киберфизических устройств и систем самого различного назначения – основного вида технических устройств середины 21 века. ИФТИС реализует «дуальную» модель образования, в рамках которой направляет студентов на стажировку и выпускников для трудоустройства на передовые предприятия, занятые созданием инновационных киберфизических продуктов, в первую очередь, на предприятия ГК «Росатом». Основным индустриальным партнером ИФТИС является ведущее предприятие ГК «Росатом» — ФГУП «ВНИИА им. Н.Л. Духова».

- ПубликацияТолько метаданныеEffect of the Magnetic Field on the Characteristics of a Pulsed Penning Ion Source(2020) Solodovnikov, A. A.; Mamedov, N. V.; Maslennikov, S. P.; Yurkov, D. I.; Мамедов, Никита Вадимович; Масленников, Сергей Павлович; Юрков, Дмитрий Игоревич© 2020, Pleiades Publishing, Ltd.Abstract: For a Penning ion generator, the dependences of the amplitude–time characteristics of the discharge current and the extracted current on the intensity and configuration of the magnetic field are studied in a regime with pulsed voltage on the anode.
- ПубликацияТолько метаданныеPenning Ion Source Discharge Modes for Pulsed and Continuous Power Supplies(2019) Mamedov, N. V.; Maslennikov, S. P.; Presnyakov, Yu. K.; Solodovnikov, A. A.; Yurkov, D. I.; Юрков, Дмитрий ИгоревичWe have analyzed the pressure dependences of the discharge and extracted currents for a Penning ion source (PIS) for continuous and pulsed power supplies. We have investigated the effect of voltage amplitude at the PIS anode, pulse repetition rate, and pulse duration on PIS amplitude-time and current-voltage characteristics. The ion source operation regimes and corresponding gas pressure ranges in which different modes of Penning discharge are realized have been determined.
- ПубликацияТолько метаданныеInvestigation of the Amplitude-Time Characteristics of a Penning Discharge in Miniature Ion Sources(2019) Rachkov, R. S.; Maslennikov, S. P.; Yurkov, D. I.; Масленников, Сергей Павлович; Юрков, Дмитрий Игоревич© 2019, Springer Science+Business Media, LLC, part of Springer Nature.Ion sources based on Penning discharge cells are now widely used in small-size pulsed neutron generators of geophysical well-logging apparatus. The operating efficiency of the apparatus is associated with the amplitude and time parameters of the neutron pulse of the generator, which depend on the gas pressure, geometry of the electrode systems, and other factors. Therefore it is necessary to investigate Penning discharge regimes in the context of control and regulation of the working gas (hydrogen) pressure as well as to measure the amplitude-time characteristics of the discharge as a function of the periodic-pulse power supply parameters. The stable discharge ignition regimes in the ion source were determined experimentally, and it was shown that different discharge regimes exist. The operating regimes of ion sources with a descending voltage dependence of the discharge current were revealed at heightened gas pressure.
- ПубликацияОткрытый доступOperation features of the pulse penning ion source in the transition pressure range(2019) Solodovnikov, A. A.; Mamedov, N. V.; Maslennikov, S. P.; Yurkov, D. I.; Мамедов, Никита Вадимович; Масленников, Сергей Павлович; Юрков, Дмитрий Игоревич© 2019 IOP Publishing Ltd. All rights reserved.The paper presents the results of experiments studying the dependence of discharge and extracted currents on the pressure of pulsed penning ion source (PIS). A comparative analysis of the amplitude-time and current-voltage characteristics of PIS for the various anode voltage amplitudes, pulse repetition rates, pulse durations, magnitudes (and configurations) of the magnetic field is presented. The obtained results reveal the existence of different (stable and unstable) discharge modes depending on the operating conditions of the power supply system and the pressure range of the working gas (deuterium). The features of current waveforms in the transitional pressure range 0.5-2 mTorr are defined.
- ПубликацияОткрытый доступMagnetic field design for miniature pulse Penning ion source(2020) Mamedov, N. V.; Gubarev, A. V.; Zverev, V. I.; Maslennikov, S. P.; Yurkov, D. I.; Мамедов, Никита Вадимович; Зверев, Владимир Игоревич; Масленников, Сергей Павлович; Юрков, Дмитрий ИгоревичMagnetic field configuration for a miniature pulse Penning ion source was designed in this work. The amplitude-time characteristics of discharge and extracted currents were investigated as a function of gas pressure for various magnetic field magnitude and configuration An effect of magnetic field configuration on the Penning's discharge modes and characteristics of the extraction current impulse were experimentally shown. Stable operation modes of the ion source were found in this work. Also the appropriate ranges of working gas pressure and magnetic field configuration were demonstrated, at which the current pulse of the extracted ions had a quasi-rectangular form. For better understanding real magnetic fields distributions of within the discharge cell magnetic field have been calculated in COMSOL software.
