摘要
在介绍 １／３整数共振引出基本理论和相关技术的同时，通过简明的解析公式，详细研究和分析了共振引出系统的布局原理．以一台小型医用质子同步加速器的磁铁聚焦结构为基础，给出了设计实例，并与计算机模拟结果进行了比较．
Based on the general theory and related technique of 1/3 integer resonant extraction, main principle of layout for momentum-amplitude selection method is studied in detail and some simple analytic formulae are given. The design of slow extraction system for Beijing Proton Therapy Synchrotron (BPTS) is then given as an example by considering its lattice. The results are also compared with simulated calculation. Study shows that an extraction beam for BPTS with extraction efficiency above 98 % and momentum spread of 0. 11 % can be obtained.
