Abstract: Crossed-field space-charge limited current (CF-SCLC) represents the maximum stable current that can be produced in crossed-field devices (CFDs); prominent CFDs include magnetrons and cyclotrons, critical technologies in vacuum electronics. While planar crossed-field geometries have the… read more here.

DOI: 10.1109/tps.2018.2844732
Abstract: The effects of a distributed cathode in a linear-format crossed-field amplifier are simulated in VSim and analyzed. A linear-format, injected-beam, 150-MHz, low-power (~100 W), moderate-gain (7 dB), meander-line crossed-field amplifier (CFA) designed and tested at… read more here.
