| Among other things, an accelerator is mounted on a gantry to enable the accelerator to move through a range of positions around a patient 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. | ||||||

| 199 | Concentric tilted double-helix dipoles and higher-order multipole magnets | US10067487 | 2002-02-05 | US06921042B1 | 2005-07-26 | Carl L. Goodzeit; Rainer B. Meinke; Millicent Ball |
| Concentric tilted double-helix magnets, which embody a simplified design and construction method for production of magnets with very pure field content, are disclosed. The disclosed embodiment of the concentric tilted double-helix dipole magnet has the field quality required for use in accelerator beam steering applications, i.e., higher-order multipoles are reduced to a negligibly small level. Magnets with higher multipole fields can be obtained by using a simple modification of the coil winding procedure. The double-helix coil design is well-suited for winding with superconducting cable or cable-in-conduit conductors and thus is useful for applications that require fields in excess of 2 T. The coil configuration has significant advantages over conventional racetrack coils for accelerators, electrical machinery, and magneto-hydrodynamic thrusting devices. | ||||||
