Abstract
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 for ion and that reduce pole diameter by increasing energy gain versus radius. An integral magnetic s…
