原始语种摘要: Proton therapy for the treatment of cancers adopts a rotating gantry to irradiate the tumor from any direction. The gantry system consists of different beamline magnets that bend the proton beam towards the patient. The use of superconducting magnets allows reducing the size and weight of the last bending section. During the gantry operation, it is necessary to change the magnetic field of the last bending section in order to vary the proton penetration depth. This change determines electrodynamic transients in the superconducting strands and cables that generate losses. A thorough computation of these losses is essential for a safe design of the cryogenic system. Two main types of losses must be accounted for when dealing with multistrand superconducting cables, related to the...
