对于海德堡/德国的诊所，建议使用“强度控制光栅扫描”方法[1，2，3，4]使用轻离子治疗癌症肿瘤的加速器设施。同步加速器的布局，这是设计用于加速碳离子从7 MeV/u的注入能量高达430 MeV/u的最大提取能量，对应于6.5 Tm的最大磁刚度。除了碳离子之外，还需要质子、氦离子和氧离子的输送。除了紧凑的同步加速器配置的概述离子光学特性和计算的主要操作阶段进行了说明。离子光学的动态变化被预见到，以满足注入和提取的要求。对于光束提取，提出了具有可变平顶持续时间的“横向敲除”程序[6]，以在提取期间保持恒定的光束光学器件，并通过在一个同步加速器循环内的多个光束提取来最小化治疗时间。
For the clinic in Heidelberg/Germany an accelerator facility is proposed for the treatment of cancer tumours with light ions using the ‘intensity controlled rasterscan‘ method [1,2,3,4]. The layout of the synchrotron is presented, that is designed to accelerate carbon ions from an injection energy of 7 MeV/u up to a maximum extraction energy of 430 MeV/u, corresponding to a maximum magnetic rigidity of 6.5 Tm. In addition to carbon ions, the delivery of protons, helium- and oxygen ions are requested as well. Beside an overview of the compact synchrotron configuration ion optical properties and calculations of the main operation phases are described. A dynamical change of the ion optics is foreseen to meet the injection and extraction requirements. For beam extraction the ‘transverse knock out‘ procedure [6] with variable flat top duration is proposed to maintain constant beam optics during extraction and to minimise the treatment time by multiple beam extraction within one synchrotron cycle.
