为了减轻用于重粒子放射治疗的旋转机架中超导磁体的重量，对一种具有主动屏蔽功能的余弦θ超导磁体进行了设计研究。主动屏蔽超导磁体由偶极线圈和主动屏蔽线圈组成。每个线圈的横截面是基于由具有NbTi细丝的超导导线的布置所制成的余弦-θ电流分布来设计的。设计研究结果表明，所设计的线圈截面能够满足磁场分布和磁体运行负载系数的要求。此外，在与具有铁轭的超导磁体的重量进行比较的同时，评估具有主动屏蔽的超导磁体的重量。因此，具有主动屏蔽的超导磁体有可能显著减轻重量。
In order to reduce the weight of superconducting magnets used in a rotating gantry for heavy particle radiotherapy, the design study of a cosine-theta superconducting magnet with active shielding was conducted. The superconducting magnet with active shielding was composed of a dipole coil and an active shield coil. The cross-section of each coil was designed, based on a cosine-theta current distribution made by the arrangement of a superconducting wire with NbTi filaments. The result of the design study indicated that the designed coil cross-sections can meet the requirements regarding the magnetic field distribution and the load factor for the magnet operation. Additionally, the weight of the superconducting magnet with active shielding was evaluated while comparing that of the superconducting magnet with an iron yoke. As a result, the superconducting magnet with the active shielding has a possibility to reduce the weight significantly.
