Abstract: The invention comprises a method and apparatus for directing charged particles into a patient from several directions. A delivery system is described that uses a primary beam line from an accelerator to a path switching magnet used to dynamically direct bunches of the positively charged particles down a selected pathway of a plurality of physically separated beam transport lines to a single patient treatment position, where the selected pathways enter the patient from two or more sides. Optionally, a repositionable treatment nozzle is repositioned to interface with each beam transport line, which allows the charged particle delivery system to use a single scanning capable nozzle in combination with delivery of the charged particles to the two or more sides of the patient to implement a tumor irradiation plan without a necessity of a moveable beamline in, at, or near a treatment room.

The transport line includes an inclination portion making the charged-particle beam travel so that the charged-particle beam is inclined to be separated from the rotation axis, and is formed to turn the charged-particle beam in a rotation direction of the rotation axis and to bend the charged-particle beam, which has turned in the rotation direction, toward the rotation axis. The rotating gantry is formed of a cylindrical portion that receives the irradiation target and supports the transport line. The inclination portion is disposed in the cylindrical portion of the rotating gantry. The charged-particle beam irradiation device further includes blocking members that block radiation emitted from the transport line disposed in the cylindrical portion.

Abstract: The invention relates to a high-temperature superconductor (HTS) magnet system, preferably for an insertion device for generation of high-intensity synchrotron radiation, consisting of the coil body (6), on the mantle surface of which poles with windings that lie between them are disposed, wherein at least one high-temperature superconductor strip (23) is wound onto the coil body (6) in one direction, and adjacent winding packages or sections are electrically connected with one another in such a manner that the current flow runs in opposite directions, in each instance. The solution according to the invention has the advantage of a simplified winding process, whereby individual coil pairs can be replaced, if necessary, by means of the modular arrangement. The scheme can be applied to every possible configuration of an insertion device, and is therefore also suitable for use in so-called free electron lasers and other light sources based on particle accelerators. Furthermore, complicated cooling is eliminated, so that safety problems caused by lack of cooling cannot occur.

Abstract: The invention comprises a charged particle beam extraction method and apparatus used in conjunction with charged particle beam radiation therapy of cancerous tumors. The system uses a radio-frequency cavity system to induce betatron oscillation of a charged particle stream. Sufficient amplitude modulation of the charged particle stream causes the charged particle stream to hit a material, such as a foil. The foil decreases the energy of the charged particle stream, which decreases a radius of curvature of the charged particle stream in the synchrotron sufficiently to allow a physical separation of the reduced energy charged particle stream from the original charged particle stream. The physically separated charged particle stream is then removed from the system by use of an applied field and deflector.
