Isochronous superconducting compact cyclotron for the magnetic structure

摘要

The present invention relates to a superconducting isochronous cyclotron for the magnetic structure to be used in the particle beam therapy. Cyclotron according to the invention, a set with three or more, the two pairs using a superconducting sector coil elements for generating a magnetic field that varies azimuthally throughout the acceleration region. Thus, isochronous cyclotron low flutter amplitude that will not suffer from problems upfield (eg greater than 4T) is provided.
