The Ion Cyclotron Resonance Accelerator (ICRA) uses a novel geometry which combines the radial confinement and azimuthal acceleration of cyclotrons together with the axial drift used in gyrotrons. Use of a common NbTi superconducting solenoid and an rf driven magnetron structure lead to a simple, lightweight, and compact machine that could be designed for portability. An ICRA designed to accele...
