Design of Prototype Magnet for Beamline System of SC200 Superconducting Proton Cyclotron

A proton therapy facility (SC200) which includes superconducting cyclotron, a gantry treatment room and a fixed beam room. The proton beams are transported mainly with beam transport devices, such as dipole magnets, quadrupole magnets and corrector magnets which lie on the beam transport system. The main purpose of this paper is to show the magnets prototype design of the beam transport line. Besides, main parameters of the magnets are presented and magnetic analysis work is also illustrated in this paper.
