Abstract
A non-scaling fixed field alternating gradient accelerator includes a racetrack shape including a first straight section connected to a first arc section, the first arc section connected to a second straight section, the second straight section connected to a second arc section, and the second arc section connected to the first straight section; an matching cells configured to match particle orbits between the first straight section, the first arc section, the second straight section, and the second arc section. The accelerator includes the matching cells and an associated matching procedure enabling the particle orbits at varying energies between an arc section and a straight section in the racetrack shape.
Claims8
A non-scaling fixed field alternating gradient accelerator, comprising:
- a first matching cell connecting a first arc section comprising permanent magnets to a second arc section comprising permanent magnets with an intermediate first straight section having at least one cavity, the first matching cell spaced about the cavity, wherein the first matching cell is configured to match particle orbits between the first straight section and the first arc section and between the first straight section and the second arc section;
- and
- a second matching cell connecting the first arc section to the second arc section with an intermediate second straight section having at least one extraction kicker, the second matching cell spaced about the at least one extraction kicker, wherein the second matching cell is configured to match particle orbits between the second straight section and the first arc section and between the second straight section and the second arc section, wherein the two arc sections have radii of approximately 2.85 meters.
