Abstract
Vacuum electron devices and linear accelerators include a hollow cathode configured to emit a beam of electrons. An anode is configured to attach and focus the beam of electrons. A control grid is configured to control the beam of electrons emitted from the hollow cathode. A cylinder is positioned substantially coaxial with the hollow cathode and is configured to maintain a shape and trajectory of the emitted beam of electrons.
Claims19
A vacuum electron device (VED), comprising:
- a hollow cathode having an emitting surface, configured to emit a beam of electrons, wherein a shape of the emitting surface is selected from the group consisting of a convex shape, a partially flat and partially concave shape, a partially flat and partially conical shape, and a partially flat and partially convex shape;
- an anode configured to attach and focus the beam of electrons;
- a control grid, having a same shape as the emitting surface, configured to control the beam of electrons emitted from the hollow cathode;
- and
- a cylinder that is substantially coaxial with the hollow cathode, configured to maintain a shape and trajectory of the emitted beam of electrons.
