Being the particle accelerator for the radiotherapy with

摘要

The present invention relates to a particle accelerator for radiation therapy with (150) ion beam. The particle accelerator comprises a (100) synchrotron ring having having (7 to 12) beam area curved and six (1-6) beam area straight six, and six parts. Injection means for introducing (100) in the synchrotron ring ion beam accelerated linearly (43), the beam area linear first (1-6) beam area straight six ( and are arranged in 1) above. Accelerating one element (44) is located along the path (5) the beam area straight at least a second for the ion beam. Extracting means for extracting the internal beam accelerated rapidly during the period of several (45) is arranged a beam area of ​​a linear third (4) on. Beam area curved of each (7 to 12) contains (13/14, 15/16, 17/18, 19/20, 21/22 and 23/24) of the dipole magnet pair. Quadrupole magnets that blur the focus horizontally (31 - 36), and between pairs (13/14, 15/16, 17/18, 19/20, 21/22 and 23/24) of each of the dipole magnet It has been placed in, quadrupole magnets to focus horizontally (25 to 30), dipole magnet pairs (13/14, 15/16, 17/18, 19/20, 21/22 and 23 of each / and is disposed upstream of the 24).
