电子冷却本质上是电子冷却作用与重离子束内散射作用的动态平衡过程.在Bjorken和Mtingwa束内散射理论的基础上,应用对称椭圆积分的方法做束内散射增长率的数值模拟,并应用于HIRFL-CSR的磁铁聚焦结构.计算结果表明,束内散射不会成为CSR磁聚焦结构设计的障碍,并且CSR可以达到冷却设计指标.

Small-angle multiple intrabeam scattering (IBS) is an important effect for heavy-ion storage rings with electron cooling, because the cooling time is determined by the equilibrium between cooling and IBS process. All usually used numerical algorithms of IBS growth rate calculations are based on the model of the collisions proposed by A.Piwinski, but this result is a multidimensional integral. In this paper, the IBS growth rates are simulated for HIRFL-CSR using symmetric elliptic integral method, and compared with several available IBS code results.
