Abstract
A magnetron which has a plurality of vanes defining resonant cavities in an anode cylinder and straps connecting equipotentially alternate vanes and is provided at both ends of the anode cylinder with a device for generating a magnetic field in an interaction space in an axial direction of the anode cylinder. The straps are made of magnetic material.
Claims6
A magnetron comprising:
- an anode cylinder,
- a plurality of inwardly projecting spaced radial vanes defining resonant cavities therebetween within the cylinder,
- a concentrically positioned cathode within the cylinder spaced from the ends of the vanes defining an interaction space between the cathode and the vanes, the cathode emitting electrons into the interaction space,
- a plurality of straps at least one of which is comprised of magnetic and electrically conductive material coupling alternate ones of the vanes at their ends adjacent the cathode to maintain equal RF potentials on alternate vanes, and
- magnetic field generating means for inducing a magnetic field in the axial direction of the cylinder in the interaction space,
- whereby the magnetic field distribution in the interaction space is aligned substantially parallel to the axial direction.
