MEQATRON: A High-Power High-Frequency RF Source

摘要

MEQATRON is an acronym for a multiple-beam electrostatic-quadrupole-focused array of electron beams. Conventional electron beam devices consist principally of single electron beams. In this paper the single-beam space-charge limitations are discussed, and a relationship for power flux (W/m exp 2 ) is obtained. Several features of the multiple-beam approach become clear at once. Because the multiple-beam approach removes the current limitation on performance, it is possible to design high-current low-voltage tubes. This fracture is important for low-frequency (200 MHz, say) klystrons. Another feature of the multiple-beam approach relates to the very small sizes (1 to 2 mm, say) associated with each beam. This offers the possibility of developing high-power rf sources in the millimeter wavelength region. (ERA citation 05:012327)
