摘　　要：近年来,离子治疗技术在国内外发展迅速。为满足加速器调试和不同治疗方案对医用回旋加速器装置的不同束流能量要求,二极磁铁电源要求工作在可相互切换的直流、有序触发和周期脉冲三种模式。使用中国科学院近代物理研究所自主研发的集成盒装式控制器,实现了对电源的控制和保护功能。为了适应调试和治疗两种不同场合的需求,控制器还支持本地和远程控制两种不同的网络协议,可通过触摸屏的控制按钮完成两者的切换。电源主回路和控制器设计并装配完成后,对各项指标进行了测试。测试结果表明,电源可正常工作在不同模式下,额定电流下长期稳定度达到了21×10^(-6),电流纹波小于万分之四,超出了设计指标。In recent years,ion therapy technology has developed rapidly in China and abroad.To meet the demands of the accelerator commissioning and the energy requirements of the different treatment scheme for the accelerator facility,the power supplies of the dipole magnets in the energy selection and beam transport system are required to work in the modes of DC,in-order trigger and periodic pulse.Using the integrated box controller independently developed by the Institute of Modern Physics,Chinese Academy of Sciences,the control and protection function of the power supply are realized.In order to meet the requirements of commissioning and treatment working modes,the controller has been designed to support the local and remote control network protocols,between which the switch can be achieved through the button on the touch screen.The power supply specifications has been tested after the main circuit and controller were designed and assembled.The test results indicate that the power supply can work well under the different modes,the long-term stability of current rating reached 21 ppm,and the current ripple was less than 0.0004,exceeding the design index.
