为分析分离函数射频四重体（SFRFQ）结构的波束动力学特性，编写了计算机代码（SFRFQCODEv1.0）。计算表明，通过选择适当的动力参数和结构参数，可以保证结构的横向和纵向稳定性。介绍了SFRFQ的束流动力学机制，并给出了SFRFQ腔体的设计实例，该腔体将用作26MHz 1MeV O+集成分裂环（ISR） RFQ的后加速器，将O+从1加速到1.5MeV。采用三个静电四倍体实现了从ISR RFQ到SFRFQ腔的横向波束匹配。此设置也适用于光束尺寸调整及其应用。
A computer code (SFRFQCODEv1.0) is developed to analyze the beam dynamics of Separated Function Radio Frequency Quadruples (SFRFQ) structure. Calculations show that the transverse and longitudinal stability can be ensured by selecting proper dynamic and structure parameters. This paper describes the beam dynamical mechanism of SFRFQ, and presents a design example of SFRFQ cavity, which will be used as a post accelerator of a 26MHz 1MeV O+Integrated Split Ring (ISR) RFQ and accelerate O+from 1 to 1.5MeV. Three electrostatic quadruples are adopted to realize the transverse beam matching from ISR RFQ to SFRFQ cavity. This setting is also useful for the beam size adjustment and its applications.
