The enlarged new edition of this textbook provides a comprehensive introduction to the
basic processes in plasmas and demonstrates that the same fundamental concepts describe …

Multi virtual cathodes (MVCs) were created in an axial vircator utilizing two dielectric
reflectors (DRs). The wall charge of drifting electrons on the surface of DRs led to the …

Having the device simplicity and high output-power capacity, the capability of the virtual
cathode oscillator (vircator) for emitting high power microwaves is demonstrated. We have …

The space-charge effects of pulsed high-current electron beams are very important to high-

Different theories which can estimate the filament temperature of the emissive probe are
compared with a two-color infrared pyrometer to evaluate the temperature acquisition …

This paper presents the investigation on the reflex triode (RT) virtual cathode oscillator
(vircator) using a carbon fiber cathode. Experimental results show that the carbon fiber …

We present a novel configuration for an axial virtual cathode oscillator (Vircator) operating in
the-band and designed for high output power applications. In order to enhance the …

A ring reflector was experimentally investigated using an axial virtual cathode oscillator
(vircator). The ring reflector was installed behind the mesh anode of the axial vircator to …
