Abstract
The present disclosure relates to a cyclotron. Embodiments of the present disclosure may include an upper and lower magnet pole, an upper and lower superconducting coil arranged around each of the magnetic poles, a ring-shaped magnetic return yoke, a beam chamber between the upper and lower magnetic poles having one or more electrodes configured to accelerate ions moving substantially in the median plane, and a cryostat. The ring-shaped magnetic return yoke and the coils may form a cold mass contained within the cryostat. Further, the cryostat may not contain the upper and lower poles.
Claims6
A cyclotron comprising:
- an upper and lower magnet pole, symmetrically placed with respect to a median plane;
- an upper and lower superconducting coil arranged around each of the magnetic poles;
- a ring-shaped magnetic return yoke, placed around the poles and the coils, configured to form a magnetic circuit;
- a beam chamber between the upper and lower magnetic poles, comprising one or more electrodes configured to accelerate ions moving substantially in the median plane, under the influence of a magnetic field oriented perpendicularly to the median plane, the field being generated by running an electric current through said coils;
- and
- a cryostat,
- wherein the ring-shaped magnetic return yoke and the coils form a cold mass contained within the cryostat, and wherein the cryostat does not contain the upper and lower poles.
