MAGNETRON SLOT MODE ABSORBER

摘要

PATENT APPLICATION of GEORGE K. FARNEY and WILLIAM A. GERARD for MAGNETRON SLOT MODE ABSORBER In a coaxial magnetron the resonant circuit interacting with the electrons is coupled to a stablizing resonator operating in a mode with circular electric field. The coupling is thru a set of slots in the intervening wall. Undesirable resonances localized in the slots are damped by lossy material at the ends of the slots. Undesirable damping of the cavity mode is prevented by a conducting shield covering exposed area of the lossy material and spaced into the cavity away from the slots.
