Solid-State Modulator for High-Power Microwave Devices with Grid Control
© 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.

Influence of External Electric Circuits on the Static and Dynamic Mode of Operation of Multipath Collectors of Powerful Klystrons
© 2020, Pleiades Publishing, Inc.Abstract—The article considers the influence of external electric circuits on the work of the collector zone with an nonstationary intense electron beam. It is shown that the presence of capacitance of the collector and inductance of the external circuit under certain conditions can lead to the appearance of large inhibitory voltage values and deterioration of the klystron output parameters. The results of experimental studies are presented.
Investigation of Discharge Generation Regimes in Penning Ion Sources Under Pulse-Packet Control
© 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.
