When small low temperature superconducting isochronous cyclotron and ion acceleration METHOD

摘要

The compact low-temperature superconducting isochronous cyclotron, and may include superconducting coils at least two per side of the median acceleration plane. Magnetic yoke surrounds the coil of these parts to accelerate the ion beam chamber, therein. And is thermally coupled to both the magnetic yoke cryogenic refrigeration system and the superconducting coils. The superconducting isochronous cyclotron comprises a sector pole tip to provide a strong focusing, the sector pole tip can be a spiral shape may be formed of a rare earth magnet. The sector pole tip can be separated from the rest of the yoke by a non-magnetic material. In other embodiments, the sector pole tip can comprise a superconducting material. The helically pole tip can also be included in the sector pole tip, a notch on the back away from the median acceleration plane. [Selection] Figure Figure 1
