摘要： There is provided a circular accelerator that accelerates a beam of charged particles circulating in a magnetic field such that a closed orbit for each energy of the beam is eccentric. The circular accelerator includes a beam extraction port for extracting beams of different energies from the closed orbit, a first bending magnet and a second bending magnet that bend the beam extracted from the beam extraction port, and a control unit that controls magnetic field strengths of the first bending magnet and the second bending magnet in accordance with the energy of the extracted beam. When the energy of the extracted beam is a designed maximum energy of the circular accelerator, the control unit excites both the first bending magnet and the second bending magnet to bend the beam.

摘要： The present invention concerns a cyclotron for accelerating a beam of charged particles over an outward spiral path until the beam of charged particles reaches a desired energy, and for extracting said beam to hit a target (20t), said cyclotron comprising:
• A vacuum chamber circumscribed by a peripheral wall (8) and comprising an opening (80),
• a target support element (20) sealingly coupled to a downstream end of the opening (80), outside the vacuum chamber, and comprising a tubular channel (20c) leading to a target holder for holding a target (20t),
• a first stripper assembly (10i) with a stripper located at a first stripping position, Pi, for stripping charged particles at a first energy, Ei,
Characterized in that, the cyclotron comprises an energy specific extraction kit for driving modified charged particles of second energy, Ej, with j ≠ i, along a second extraction path, Sj, through the opening in the peripheral wall, along the tubular channel, and towards the target holder, wherein the energy specific extraction kit comprises,
• a second stripper assembly (10j) with a stripper located at a second stripping position, Pj, for stripping charged particles at a second energy, Ej,: and
• an insert (21j) to be sandwiched between the downstream end of the opening (80) and the target support element (20) with an insert channel (21c) for modifying an orientation of the tubular channel to match the second extraction path, Sj, such that the modified charged particles of second energy, Ej, intercept the target holder.-

摘要： An example particle accelerator includes the following: a resonant cavity in which particles are accelerated, where the resonant cavity has a background magnetic field having a first shape; and an extraction channel for receiving particles output from the resonant cavity. The extraction channel comprises a series of focusing regions to focus a beam of received particles. At least one of the focusing regions is a focusing element configured to alter a shape of the background magnetic field to a second shape that is substantially opposite to the first shape in the presence of a magnetic field gradient resulting from reduction of the background magnetic field from the resonant cavity to the extraction channel.

摘要： A charged hadron therapy system (100) for delivering charged hadron radiation to a target is provided. The system comprises a target positioning couch (15) for supporting the target being moveable along a translation direction (Y') and a beam delivery system (10) comprising a beam scanning means (13) for scanning a hadron pencil beam over said target in an first scanning direction (X) and a second scanning direction (Y) being substantially parallel with the translation direction (Y'). The beam scanning means (13) is limited for providing a maximum scanning amplitude AY in the second scanning direction (Y'). The system comprises an irradiation controller (16) configured for simultaneously and synchronously performing the moving of the couch and the scanning, so as to deliver charged hadron radiation to a target over a target size being larger in the Y direction than the maximum scanning amplitude AY.

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 charged particle beam irradiation system and a charged particle beam extraction method which can prevent erroneous irradiation of a charged particle beam in the direction of advance of the charged particle beam. The system and method are featured in stopping supply of an ion beam to one or more of a plurality of angle zones in each of which a target dose is attained, the angle zones being formed by dividing a range modulation wheel (RMW) (202) in a rotating direction thereof, and in allowing the supply of the ion beam to one or more other angle zones in each of which a target dose is not yet attained. The invention can easily adjust beam doses at various positions in an affected part (216a) of the patient body (216) in the direction of advance of the ion beam, and can greatly reduce the probability of erroneous irradiation that the beam dose becomes excessive or deficient at the various positions within the affected part of the patient body in the direction of advance of the ion beam.
