商业回旋加速器广泛采用内离子源来生产短寿命的同位素。如果没有外部注入线提供的束流操控，这种类型的回旋加速器的中心区更敏感，应该仔细设计。介绍了一台10 MeV小型回旋加速器中心区的设计研究和束流动力学模拟。用OPERA3D/TOSCA程序从一个参数化的三维中心区模型计算电场。通过对中心区的迭代结构优化，光束中心和垂直聚焦得到了很好的控制，射频相位接受度达到25°左右。开发了用于中心区束流模拟的C++程序，并对其进行了测试。
Internal ion sources are widely adopted in commercial cyclotrons used for short-life isotopes production. Without beam manipulation provided by the external beam injection line, the central region of this type of cyclotron is more sensitive and should be carefully designed. A design study and beam dynamics simulation for the central region of a 10 MeV compact cyclotron is presented. The OPERA3D/TOSCA code was used to calculate the electric field from a parameterized three dimensional (3D) central region model. With iterative structure optimizations of the central region, the beam centering and vertical focusing is well controlled, and the RF phase acceptance is around 25°. A c++ code for beam simulation in the central region was developed and tested.
