Abstract
A new design is presented for a superconducting-coil-based compact cyclotron, which has many practical benefits over conventional superconducting cyclotrons. Unlike in conventional superconducting cyclotrons, an iron yoke and poles have been avoided in this design and the azimuthally varying field is generated by superconducting sector coils. Housing the superconducting sector coils and circular coils in a single cryostat has resulted in an ultralight 25 MeV proton cyclotron weighing about 2000 kg. Further, the sector coils and the main coils are fed by independent power supplies, which allow flexibility of operation through on-line magnetic field trimming. The engineering considerations, focused on making the cyclotron ideally suited to medical applications, are described in detail.
