| 摘 要： | 随机冷却系统有助于提高兰州重离子冷却储存环（ＣＳＲ）中束流累积效率，减小束流发射度．首先通过Ｆｏｋｋｅｒ－Ｐｌａｎｃｋ方程的建立，解出了某种初始分布下粒子分布的时间演化结果，并模拟了冷却过程；然后结合ＣＳＲ物理设计参数，计算了部分典型被加速离子的冷却时间，同时比较了电子冷却和随机冷却的冷却力，得出了一些结论；最后提出了硬件设计方案. Stochastic cooling system in Cooling Storage Ring (CSR) at Lanzhou will help to cool beam phase space and increase the accumulation ratio and efficency. In this paper, a Fokker Planck eqution is described and used to simulate cooling process.According to the main parameters of CSR,cooling time of some typical ions has been calculated and the cooling forces of electron cooling and stochastic cooling are compared. Finally, A hardware designing plan is proposed.
