Quadrupole Strong Focusing for Space-Charge Dominated Electron Beams in Traveling-Wave Tubes
Abstract
dc:description.abstractAnalysis of quadrupole focusing lattices for high-frequency TWTs is presented. This work is motivated by recent work performed at the Naval Research Laboratory (NRL) which demonstrated an advantageous case for strong focusing employing a Halbach quadrupole lattice. Using realistic Permanent Magnet Quadruple (PMQ) field cancellation, the advantage of using PMQ to transport higher current densities than Permanent Periodic Magnet (PPM) lattices disappears, while other advantages for employing quadrupole focusing remain. This dissertation gives a comprehensive analysis of the applicability of PMQ focusing in vacuum electronic devices.'
