在100MeV强流回旋加速器调试过程中,需对束流在加速器内的轴向和径向参数进行测量。径向靶系统是束流诊断系统中用于获取上述参数的主要部件,本文研制了3套阻挡式径向靶系统,并安装到加速器主体,获得了束流在连续加速过程中的轴向和径向分布,为加速器运行提供了相应束流参数,并为后续加速器升级工作提供了必要的条件。 During the commissioning of a 100MeV strong current cyclotron, the axial and radial parameters of the beam in the accelerator must be measured. The radial target system is the main component of the beam diagnostic system for obtaining the above parameters. In this paper, three sets of radial target systems are designed and installed in the accelerator body to obtain the axial and Radial distribution provides the corresponding beam parameters for accelerator operation and provides the necessary conditions for subsequent accelerator upgrade.
