Investigation of Discharge Generation Regimes in Penning Ion Sources Under Pulse-Packet Control
(2021) Maslennikov, S. P.; Struchenkova, O. G.; Mamedov, I. M.; Maslennikova, I. S.; Масленников, Сергей Павлович
© 2022, Springer Science+Business Media, LLC, part of Springer Nature.The efficiency and effectiveness of logging equipment are largely determined by the amplitude-time characteristics of neutron fluxes, which depend on the parameters of the magnetic field generating systems, anode voltage pulses, gas composition, gas pressure, and others. The processes of restoration of the breakdown strength of gas in the interelectrode gap during the pauses between the supply voltage pulses affect the discharge ignition conditions and stability of the neutron flux characteristics. The results of experimental investigations of the pulse-packet operating regimes of Penning ion sources under conditions of wide adjustment of the parameters of the control and power systems for neutron tubes are reported.

Solid-State Modulator for High-Power Microwave Devices with Grid Control
(2019) Komarov, D. A.; Maslennikov, S. P.; Масленников, Сергей Павлович
© 2019, Pleiades Publishing, Inc. Abstract: A solid-state pulse modulator for high-power microwave devices with grid control has been designed and tested. The output stage of this modulator uses a switching unit with two microsecond-band high-voltage switches toggled in antiphase. These switches were constructed on series-connected MOS transistors, have nanosecond switching times, and operate at voltages of as high as 10 kV. The modulator has demonstrated stable operation in tests performed to evaluate its potential to control high-power microwave devices.

Investigation 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.

Characteristics of miniature pulsed penning ion source: Experiment and PIC simulation
(2019) Mamedov, N.V.; Rohmanenkov, A.S.; Zverev, V.I.; Maslennikov, S.P.; Yurkov, D.I.; Мамедов, Никита Вадимович; Зверев, Владимир Игоревич; Масленников, Сергей Павлович; Юрков, Дмитрий Игоревич
In the present work, the results of the experimental and particle in cell (PIC) simulation studies of the discharge combustion modes in a miniature Penning ion source (PIS) under the pulse-periodic power supply conditions are presented. Dynamics of discharge ignition and discharge operation mode at a pulsed anode voltage supply are investigated for different values of anode voltage and gas pressure in various magnetic field configurations. Typical examples of current pulse waveforms are shown. Also, numerical simulations of the PIS were performed using 3D PIC combined with Monte Carlo collisions in the code VSim. Temporal dependencies of electron, ion, and potential distributions in the Penning cell are simulated. Differences between the numerical and experimental results are discussed.
