Abstract
A multi-mode radio frequency cavity provides both an electric field and a magnetic field therein. Another aspect provides an apparatus including a radio frequency gun, at least one radio frequency power supply and a dual-mode electron bunching cavity. In another aspect, a radio frequency cavity includes both an on-axis/on-equator tuner and an off-axis/off-equator tuner. A method of using a radio frequency cavity with a radio frequency cavity with both on-axis/on-equator cavity tuning and an off-axis/off-equator cavity tuning, is provided in yet another aspect.
Claims23
A radio frequency apparatus comprising:
- a radio frequency cavity including a hollow body with a curved interior surface therein;
- an electron entry port configured to allow electrons to enter into the body;
- an electron exit port configured to allow electrons to exit the body;
- an electrical field coupler having a distal end located within the body;
- a magnetic field coupler having a distal end located within the body, the couplers being spaced apart from each other;
- at least one radio frequency generator connected to the couplers;
- and
- the couplers being configured to provide both an electric field and a magnetic field within the same cavity.
A radio frequency apparatus comprising:
- a radio frequency cavity;
- an electron entry port configured to allow electrons to enter into the cavity;
- an electron exit port configured to allow electrons to exit the cavity;
- a harmonic mode coupler having a distal end located within the cavity;
- a fundamental mode coupler having a distal end located within the cavity, the couplers being spaced apart from each other;
- a first of the couplers being located on-equator of the cavity;
- a second of the couplers being located off-axis and off-equator of the cavity;
- and
- the couplers being configured to provide both an electric field and a magnetic field within the same cavity.
A radio frequency apparatus comprising:
- a radio frequency cavity;
- an electron entry port configured to allow electrons to enter into the cavity;
- an electron exit port configured to allow electrons to exit the cavity;
- an electrical field coupler having a distal end located within the cavity;
- a magnetic field coupler having a distal end located within the cavity, the couplers being spaced apart from each other;
- and
- a radio frequency tuner operably advancing or retracting to change a shape of an interior surface of the cavity and to change an internal volume of the cavity, which changes radio frequency modes associated with the cavity.
