紧凑型中高能同步加速器的物理设计

摘要

本文采用束流光学匹配软件优化组合磁铁布局得到一种紧凑型的同步加速器。该加速器具有周长短、磁铁孔径小、束流品质高等优点。注入和引出设计是此同步加速器的关键点，基于M atlab／A T开发了模拟软件，模拟研究注入和引出相关束流动力学问题。研究结果表明，该同步加速器束流品质优、注入效率高、引出束流损失低。该同步加速器可满足航天、材料和生物等多方面研究。%A compact synchrotron was designed based on beam optical software .The ad‐vantages of the synchrotron are small circumference ,small aperture of magnet and high beam quality .The design of injection and extraction is very important for the synchro‐tron .Based on Matlab/AT ,a simulation code of injection and extraction was devel‐oped ,and the dynamic of injection and extraction process was studied .The result shows that the beam in the synchrotron has high quality ,high injection rate and low beam loss in extraction process .The synchrotron can be used to study of spaceflight ,material and biology.
