    摘要： A magnet structure for particle acceleration includes at least two coils that include a continuous path of superconducting material (e.g. niobium tin (Nb3Sn) having an A15-type crystal structure) for electric current flow there through. The coils can be mounted in a bobbin, which together with the coils form a cold-mass structure. The coils are cooled to their superconducting temperatures via cryocoolers. Radial-tension members are coupled with the cold-mass structure to keep it centered, such that it remains substantially symmetrical about a central axis and is not pulled out of alignment by magnetic forces acting thereon. A wire can be wrapped around the coils, and a voltage can be applied thereto to quench the coils to prevent their operation of the coils in a partially superconducting condition, which may otherwise cause damage thereto. A magnetic yoke surrounds the cold-mass structure and includes a pair of poles that, in part, define an acceleration chamber there between. The inner surfaces of the poles have tapered profiles that establish a correct weak focusing requirement and that provide phase stability for ion acceleration and that reduce pole diameter by increasing energy gain versus radius. An integral magnetic shield is positioned about the yoke to contain magnetic fields emanating there from and can have a tortuous configuration to contain magnetic fields having a variety of orientations. The magnet structure can be very compact and can produce particularly high magnetic fields.

    摘要： The magnetic field in an acceleration chamber defined by a magnet structure is shaped by shaping the poles of a magnetic yoke and/or by providing additional magnetic coils to produce a magnetic field in the median acceleration plane that decreases with increasing radial distance from a central axis. The magnet structure is thereby rendered suitable for the acceleration of charged particles in a synchrocyclotron. The magnetic field in the median acceleration plane is 'coil-dominated,' meaning that a strong majority of the magnetic field in the median acceleration plane is directly generated by a pair of primary magnetic coils (e.g., superconducting coils) positioned about the acceleration chamber, and the magnet structure is structured to provide both weak focusing and phase stability in the acceleration chamber. The magnet structure can be very compact and can produce particularly high magnetic fields.

    摘要： The invention relates to a coil for producing a magnetic field having at least one winding (12), which is manufactured from a superconductor, is cast into a plastic and whose winding end (19) which is arranged at the circumference (13) of the winding (12) is used for making contact with an electrical conductor (15). In order to provide coils with windings (12) consisting of superconductors which make robust contact-making possible given simple production, an electrically conductive connection piece (30) with a base region (31), which is connected areally to the winding end (19), and a top region (32) for connecting the conductor (15) is provided for contact-making purposes, the base region (31) of said connection piece (30) being covered partially in the radial direction by a reinforcing insert (14), which is cast into the plastic (20) and at least partially surrounds the winding (12).
