It has been developed to disseminate open access research outputs, expose data about those outputs, and enable the management and persistent access to Strathclyde's intellectual output. The design and simulation of a G-band extended interaction oscillator (EIO) driven by pseudospark-sourced electron beam is presented. The characteristic of the EIO and the pseudospark-based electron beam are studied to enhance the performance of the newly proposed device. The beam-wave interaction of the EIO can be optimized by choosing a suitable pseudospark discharging voltage and by widening the operating voltage region of the EIO circuit. Simulation results show that a peak power over 240W can be achieved at G-band using a pseudospark discharging voltage of 41kV.

Compact millimetre wave and terahertz radiation sources driven by pseudospark-generated electron beam

“…During a PS discharge, low temperature plasma is formed that acts as a copious source of electrons facilitating electron extraction to form electron beam of diameters in the range from millimetre to microns. The propagation property of this PS sourced beam is further investigated experimentally and in simulation, which proved the beam's propagation without external guiding magnetic field and its potential applications in the generation of millimetre wave and sub terahertz radiation [5][6][7][8].…”

Investigation of millimeter wave extended interaction oscillation using improved pseudospark-sourced electron beams

“…This makes it an excellent electron beam source for desirable compact millimeter wave devices. Among various vacuum electronic devices, the EIO as a linear beam vacuum device has gained considerable attention as a promising millimeter wave oscillation source due to its high gain per unit length and compact configuration [4][5][6][7].…”

Preliminary design of a G-band extended interaction oscillator driven by a sheet electron beam

“…The extended interaction oscillator (EIO) has been widely studied as a promising source to satisfy some of these applications, due to its high radiation power and compact configuration [1][2]. Compared with pencil electron beam vacuum electron devices (VEDs), sheet beam devices have attracted considerable attention as they produce radiation power proportional to the beam width and reduce the electron beam current density, leading to low magnetic field strengths required for beam focusing, thereby enabling periodic-permanent-magnet (PPM) focusing [5][6][7].…”

“…In the millimeter and sub-millimeter wavelength community, RF sources with compact configuration, high efficiency, and high output power have many potential applications, including satellite communications, radars, molecular spectroscopy, bioimaging, and plasma science [1][2][3][4][5][6][7][8][9][10][11]. The extended interaction oscillator (EIO) has been widely studied as a promising source to satisfy some of these applications, due to its high radiation power and compact configuration [1][2].…”
