Effects of electron beam focusing on virtual cathode formation in virtual cathode oscillator

2016 IEEE International Conference on Plasma Science (ICOPS), 2016
As a high power microwave (HPM) source, virtual cathode oscillator has been studied due to its simplicity. A lot of experiments on virtual cathode oscillator has been conducted and reported to study the characteristics and to increase its efficiency1, 2. In order to increase its efficiency, ballistic focusing of an electron diode has been studied3. And

Efficient Magnetron With a Virtual Cathode

IEEE Transactions on Plasma Science, 2016
We use particle-in-cell (PIC) computer simulations to demonstrate high-efficiency operation of a magnetron with diffraction output (MDO) that uses a virtual cathode in the interaction space instead of a physical cathode. The cathode generating the electron beam is external to the MDO interaction space and, therefore, is immune from electron bombardment,

Studies of virtual cathode characteristics near thermionic emission cathodes in a vacuum

Vacuum, 2021
Abstract The “virtual cathode” structure formed by the space charge near a thermionic emission cathode has a great influence on the characteristics of the emissive probe. The relationship between the characteristics of the virtual cathode in a vacuum and the probe filament temperature is not clear.

Hybrid microwave oscillators with a virtual cathode

Plasma Physics Reports, 2004
A review is given of the developments and theoretical investigations of a fundamentally new class of microwave devices, namely, hybrid microwave oscillators with a virtual cathode, which combine the useful properties of virtual cathodes with the advantages of those traditional microwave oscillators that operate with subcritical-current beams and have a
