摘要： Among other things, an accelerator (502) is mounted on a gantry (504) to enable the accelerator to move through a range of positions around a patient (506) on a patient support. The accelerator is configured to produce a proton or ion beam having an energy level sufficient to reach any arbitrary target in the patient from positions within the range. The proton or ion beam passes essentially directly from the accelerator to the patient. In some examples, the synchrocyclotron has a superconducting electromagnetic structure that generates a field strength of at least 6 Tesla, produces a beam of particles having an energy level of at least 150 MeV, has a volume no larger than 4.5 cubic meters, and has a weight less than 30 Tons.

摘要： The invention relates to an undulator (10) for producing synchrotron radiation from a particle stream (1) introduced into the undulator, said stream particularly comprising electrons. The undulator (10) comprises two partial undulators (11, 12), each having a winding body for receiving a coil package and a plurality of magnetic poles of the undulator. The winding body alternately comprises a plurality of first layers (21, 21', 21'', …), each having a non-magnetic material over which the coil package is guided, and second layers (22, 22', 22'', …), each having a soft magnetic material, serving as poles of the undulator, said layers being attached parallel to one another. The undulator according to the invention furthermore comprises lateral correction coils (31, 31', …) that are attached to selected second layers and enable effective local field error correction.

摘要： The invention relates to a particle accelerator for radiotherapy by means of ion beams (150). The particle accelerator comprises a sixfold synchrotron ring (100) with six rectilinear beam sections (1 to 6) and six curved beam sections (7 to 12). Injection means (43) for introducing a linear-accelerated ion beam into the synchrotron ring (100) are situated on a first rectilinear beam section (1) of the six rectilinear beam sections (1-6). At least one acceleration element (44) for the ion beam is located along the course of a second rectilinear beam section (5). Extraction means (45) for extracting the internal beam that has been rapidly accelerated during several revolutions are situated on a third (4) rectilinear beam section. Each curved beam section (7 to 12) comprises a pair of dipole magnets (13/14, 15/16, 17/18, 19/20, 21/22, 3/24). A horizontally defocusing quadrupole magnet (31 to 36) is located between each pair of dipole magnets (13/14, 15/16, 17/18, 19/20, 21/22, 23/24) and a horizontally focusing quadrupole magnet (25 to 30) is located upstream of each dipole magnet pair (13/14, 15/16, 17/18, 19/20, 21/22, 23/24).

摘要： The invention comprises a patient positioning and/or repositioning system, such as a laying, semi-vertical, or seated patient positioning, alignment, and/or control method and apparatus used in conjunction with multi-axis charged particle radiation therapy. Patient positioning constraints optionally include one or more of: a seat support, a back support, a head support, an arm support, a knee support, and a foot support. One or more of the positioning constraints are preferably movable and/or under computer control for rapid positioning, repositioning, and/or immobilization of the patient. The system optionally uses an X-ray beam that lies in substantially the same path as a proton beam path of a particle beam cancer therapy system. The generated image is usable for: fine tuning body alignment relative to the proton beam path, to control the charged particle beam path to accurately and precisely target the tumor, and/or in system verification and validation.

摘要： A particle therapy system capable of confirming energy of an accelerated charged particle beam before the charged particle beam is irradiated to an irradiation target. A beam position monitor is disposed in a synchrotron, and a cavity voltage monitor is associated with an RF cavity for acceleration. An ion beam orbiting within the synchrotron is accelerated with application of an RF voltage applied to the RF cavity and is extracted from the synchrotron with application of an RF voltage applied to an RF knockout electrode. Based on a cavity voltage signal detected by the cavity voltage monitor, a frequency counter measures the frequency of the RF voltage applied to the RF cavity. Based on a voltage detected by the beam position monitor, a beam signal processing unit measures the position of a beam orbit. Based on the frequency of the RF voltage and the position of the beam orbit, the energy judgment processing unit determines whether energy of the ion beam after the end of the acceleration is normal or abnormal.

摘要： An SOR light generating apparatus in which an SOR light generated from the charged particles circulating along a circular orbit in the form of a bunch at speeds close to the speed of light, is reflected by a reflector which is so arranged as to surround the circumference of the orbit in order to accumulate the SOR light in the reflector and to guide it to a light take-out port. Using a reflector having a curvature with which the reflected SOR light comes into contact with the orbit of the charged particles, the SOR light generated at a contact point is guided to the light take-out port along the light path same as the reflected SOR light. Therefore, efficiency for utilizing the SOR light is markedly improved. Further, the SOR light generated from a given bunch is reflected and is permitted to be incident on another bunch and, moreover, the SOR light emitted from the head of a given bunch is permitted to be incident on the tail portion of the same bunch, in order to obtain a short pulse having a large strength. By causing the SOR lights from the bunches and the reflected SOR lights to be interfered by each other, it is possible to obtain a monochromatic SOR light. Laser oscillation can also be effected by disposing a diffraction grating on at least a portion of the reflector to select a wavelength of SOR light or by projecting a laser beam from an external unit.
