A pseudospark (PS) discharge can generate an electron beam with a high current density.
The electron beam can be self-focused by an ion channel and transported over a long …

We present the theory, concept and design of an efficient, megawatt coherent Cherenkov
radiation source based on a two-dimensional periodic surface lattice (2D-PSL) cavity …

In this article, the design approach for a-band miniaturized oscillator with a pseudospark-
based high-current-density sheet electron beam source is presented. The hollow cathode …

Used widely in microwave devices and material processing, triggered pseudospark
discharge can generate an electron beam, the adjustability of which is affected greatly by the …

Normally, the conventional sheet beam extended interaction oscillator (SB-EIO) operates in
a single mode and has a narrow tunable bandwidth. To broaden the tunable bandwidth, the …

A backward wave oscillator (BWO) based on a double-staggered grating (DSG) slow wave
structure (SWS) is investigated as a high-power wideband terahertz (THz) source, driven by …

Pseudospark (PS) discharge-based electron beam sources are capable of generating high
current density, high energy, high emittance, and high brightness self-focused electron …

Our previous experimental study of a 0.2-THz extended interaction oscillator (EIO) driven by
the pseudospark-sourced (PS) sheet electron beam has revealed one key issue: the …

In this article, the electrical characterization of a plasma-assisted electron beam source with
a sub-mm sheet aperture has been performed. The developed sheet electron beam source …

Pseudospark discharge is a discharge that occurs in the left band of the Paschen curve.
According to previous studies, an electron beam will be generated in the initial stage of …
