Abstract
The invention relates to a particle accelerator for radiotherapy by means of ion beams (). The particle accelerator comprises a sixfold synchrotron ring () having six rectilinear beam sections (to) and six curved beam sections (to). Injection means () for introducing a linearly accelerated ion beam into the synchrotron ring () are arranged on a first rectilinear beam section () of the six rectilinear beam sections (-). Along the course of a second rectilinear beam section () there is at least one acceleration means () for the ion beam. Extraction means () for extracting the internal beam highly accelerated after several circulations are provided on a third rectilinear beam section (). Each curved beam section (to) comprises a pair of dipole magnets (). A horizontally defocusing quadrupole magnet (to) is arranged between each pair of dipole magnets (), and a horizontally focusing quadrupole magnet (to) is arranged upstream of each pair of dipole magnets ().
