用来自同步加速器的碳等轻离子束治疗肿瘤是一种局部加速器应用。在所有设计中，注入器直线加速器的布局是关于这种医疗设施的构造和操作成本以及操作性能的重要因素。两个替代的直线加速器的方法，保持尽可能低的组件和设置参数的数量进行了讨论。在这两种情况下，叉指H型漂移管结构用于将C/sup 4+/离子从0.3 MeV/u加速到7 MeV/u。一种是采用“组合零度结构”KONUS;另一种是采用“交替相位聚焦”的有源滤波器，没有任何用于横向聚焦的磁四极。这两种设计进行了调查与LORASR代码。由于相同的直线加速器也应该提供几毫安的束流强度的质子，比较扩展到加速强离子束的能力。
Tumor therapy with light ion beams like carbon out of a synchrotron is a topical accelerator application. In all designs the layout of the injector linac is an important factor with respect to construction and operation costs as well as to the operation performance of such a medical facility. Two alternative linac approaches which keep the number of components and setting parameters as low as possible are discussed. In both cases the interdigital H-type drift tube structure is used for acceleration of C/sup 4+/ ions from 0.3 MeV/u to 7 MeV/u. The "Combined Zero Degree Structure" KONUS is used in one design; the other approach is "Alternating Phase Focusing" APF without any magnetic quadrupoles for transverse focusing. Both designs were investigated with the LORASR code. As the same linac should also provide protons with beam intensities of a few mA, the comparison was extended towards the capability of accelerating intense ion beams.
