A superconducting cyclotron is provided that includes a superconducting magnet. This superconducting magnet is arranged to provide a magnetic field that extends axially through a chamber which includes a radially extending beam space. There is further an interaction within the chamber between the axially extending magnetic field and RF energy that energizes particles that are circulating within the beam space. There is further a linear accelerator that is aligned with and exposed to the axially extending magnetic field of the superconducting cyclotron. The output of this linear accelerator communicates with an input to the beam space so that the particles for acceleration within the beam space are pre-accelerated by the linear accelerator. |
