论文摘要
高频线性加速器非常适合碳离子治疗，这要归功于运营成本的降低以及相对于同步加速器的远光灯质量，目前，这是该应用程序的唯一可用技术。在开发新的碳离子疗法的新拉纳克的框架内，本文介绍了用梯形叶片的紧凑型750 MHz射频四极杆（RFQ）的设计。引入了一种新的半分析方法来设计梯形 - vane RFQ，并与相关的束动力学特性一起引入。 RFQ分为两个解耦的RF腔，两者都通过长度调节使用了一种新型的偶极偶极功能。从RF和梁动力学的角度描述了分裂。本文以完整结构的RF设计结束，包括最大的表面场和热研究。
High-frequency linear accelerators are very suitable for carbon ion therapy, thanks to the reduced operational costs and the high beam quality with respect to synchrotrons, which are presently the only available technology for this application. In the framework of the development of a new linac for carbon ion therapy, this article describes the design of a compact 750 MHz Radio Frequency Quadrupole (RFQ) with trapezoidal vanes. A new semi-analytic approach to design the trapezoidal-vane RFQ is introduced together with the relevant beam dynamics properties. The RFQ is split into two decoupled rf cavities, both of which make use of a novel dipole detuning technique by means of length adjustment. The splitting is described both from the rf and the beam dynamics point of view. The paper concludes with the rf design of the full structure, including maximum surface field and thermal studies.
