Description
Various types of magnets, including dipole, quadrupole, sextupole and combined-function type, are used for beam transportation and delivery in proton therapy systems (PTS). Toward urgent demands for lightweight PTS, we will discuss the opportunities and challenges on magnet design issues, especially for gantry beamline. Two gantry beamline design schemes will be introduced and compared: (1) a superconducting gantry using combined-function curved AG-CCT magnets, (2) a compact normal-conducting gantry with optimized layout. The former scheme also exhibits large energy momentum acceptance feature, that has potential clinical applications. Other topics, including compact scanning magnets and optimizations on normal-conducting magnets for beam delivery in PTS, will be discussed. This paper try to extract essential and common factors in this research area, based upon existing literatures and research works performed at HUST.
