(Color online) Cutaway views of the A6 magnetron with six metal tuners (a) in the plane at azimuthal center of open cavity and (b) in the plane at location of .
(Color online) Three rf magnetic field contour plots of the mode for the A6 magnetron: (a) uniform field without the metal tuner, (b) perturbed magnetic field with three metal tuners spaced 120° apart, and (c) perturbed magnetic fields with three metal tuners asymmetrically inserted into the six resonators.
(Color online) Electron plots (a) in the plane and (b) in the plane. Three metal tuners are asymmetrically inserted into the cavity at . The Cross sectional view of the plane is at the location of .
(Color online) Frequency spectra of the rf voltage at the waveguide output for the two cases. Thin line indicates the spectrum of the rf voltage with uniform RF magnetic fields, and the thick line indicates the spectrum of the rf voltage with asymmetrically perturbed rf magnetic fields by the asymmetric tuners.
(Color online) Output characteristics of the A6 magnetron with three metal tuners asymmetrically inserted: (a) open circles indicate the radiation output powers and (b) filled squares indicate the tuned resonant frequencies as a function of the axial tuner position.
