Abstract
Various embodiments of a vacuum electronic device, a hybrid magnet for a vacuum electronic device and methods of making a hybrid magnet for a vacuum electronic device are disclosed herein. In one embodiment, a hybrid magnet for a vacuum electronic device includes a first magnet, a second magnet positioned in spaced-apart relation with the first magnet and defining a gap between the first magnet and the second magnet, and a non-magnetic spacer positioned in a portion of the gap between the first magnet and second magnet and connected to the first magnet and the second magnet.
Claims19
A hybrid magnet for a vacuum electronic device comprising:
- a first magnet magnetic disk segment;
- a second magnet magnetic disk segment positioned in spaced-apart relation with the first magnet magnetic disk segment and defining a gap between the first magnet magnetic disk segment and the second magnet magnetic disk segment;
- and
- a non-magnetic spacer positioned in a portion of the gap between the first magnet magnetic disk segment and the second magnet magnetic disk segment and connected to the first magnet magnetic disk segment and the second magnet magnetic disk segment,
- wherein another portion of the gap between the first magnetic disk segment and the second magnetic disk segment comprises an RF port opening in the hybrid magnet.
A method of manufacturing a hybrid magnet for a vacuum electronic device, the method comprising:
- forming a first magnetic disk segment and a second magnetic disk segment from a disk magnet;
- and
- connecting a non-magnetic spacer between the first magnetic disk segment and the second magnetic disk segment, leaving an RF port entry opposite the non-magnetic spacer between the first magnetic disk segment and the second magnetic disk segment.
A vacuum electronic device comprising:
- a vacuum housing;
- an electron gun at a first end of the vacuum housing;
- a collector at a second end of the vacuum housing;
- a plurality of annular magnets positioned along and around the vacuum housing with the vacuum housing passing through axial tunnels through the plurality of annular magnets;
- and
- at least one hybrid magnet positioned around the vacuum housing, the at least one hybrid magnet having an annular shape with an axial tunnel for the vacuum housing, an RF port opening on a first side and a non-magnetic spacer symmetrically positioned on a second side around the axial tunnel, the at least one hybrid magnet being axially magnetized, wherein the at least one hybrid magnet produces a substantially symmetrical magnetic field around the vacuum housing.
