摘要:

我们提出了一种创新的线性加速结构,特别适合强子治疗应用。它的两个主要特点是结构紧凑,在低束速下具有良好的功率效率:第一个是通过高工作频率和随之而来的高加速梯度实现的,第二个是通过将几个H模腔耦合在一起获得的。该结构被称为CLUSTER,代表“使用横向电径向场的耦合腔直线加速器”。为了比较这种结构的性能与其他强子治疗直线加速器的设计,涉及高频率,已进行了概念性研究的工作频率为3 GHz。此外,通过在1 GHz下工作的原型上进行RF测量,获得了原理证明。使用CLUSTER直线加速器的加速器复合体也被考虑用于质子治疗目的。整个复合体被称为回旋加速器,由一个商业回旋加速器组成,将束注入高频直线加速器。

英文摘要:

We propose an innovative linear accelerating structure, particularly suited for hadrontherapy applications. Its two main features are compactness and good power efficiency at low beam velocities: the first is achieved through a high working frequency and a consequent high accelerating gradient, the second is obtained by coupling several H-mode cavities together. The structure is called CLUSTER, which stands for "Coupled-cavity Linac USing Transverse Electric Radial field". In order to compare the performance of this structure with other hadrontherapy linac designs involving high frequencies, a conceptual study has been performed for an operating frequency of 3 GHz. Moreover a proof of principle has been obtained through RF measurements on a prototype operating at 1 GHz. An accelerator complex using a CLUSTER linac is also considered for protontherapy purposes. The whole complex is called cyclinac and is composed of a commercial cyclotron injecting the beam in a high-frequency linac.
