串列加速器升级工程中100 MeV质子回旋加速器的质子束流管道系统中,北向引出的束流先在北线公共质子管道中传输,然后经±30o的北线开关磁铁被分配至ISOL和同位素研制两条管道中。所设计的北线开关磁铁应有能力将75~100 MeV的质子束流偏转30o。1理论设计在理论设计中,根据100 MeV质子束的磁刚度及该区域束流包络尺寸,并综合考虑建造、运行成本等因素,初步拟定了北线开关磁铁设计参数,如表1所列。
In the proton beam pipeline system of the 100 MeV proton cyclotron in the tandem accelerator upgrade project, the beam from the north is firstly transmitted in the common proton pipelines of the north line and then distributed to the ISOL and isotope development via ± 30o north line switched magnets Two pipes. The designed North-line switched magnets should have the ability to deflect a proton beam of 30-100 at 75-100 MeV. 1 Theoretical Design In the theoretical design, according to the magnetic stiffness of 100 MeV proton beam and the beam envelope size in this area, the design parameters of the north line switched magnet are preliminarily formulated according to the factors of construction and operation costs, as shown in Table 1 .
