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.
Claims20
A vacuum electron device (VED), comprising:
- a hollow cathode configured to emit a beam of electrons;
- an anode configured to attach and focus the beam of electrons;
- a control grid 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.
A linear accelerator, comprising:
- an electron gun that includes:
- a hollow cathode configured to emit a beam of electrons;
- an anode configured to attach and focus the beam of electrons;
- a hollow grid configured to control the beam of electrons emitted from the hollow cathode;
- and
- a cylinder that is substantially coaxial with the hollow cathode and that is positioned within the hollow grid, configured to maintain a shape and trajectory of the emitted beam of electrons;
- and
- a plurality of resonant cavities configured to accelerate the beam of electrons.
The linear accelerator of 16, further comprising a target, positioned in a path of the beam of electrons, that is configured to generate x-ray photons upon impact by electrons in the electron beam.
