摘　　要：对拟在HIRFL CSRm上建造的横向自由振荡随机冷却进行了数值优化计算和设计 ,得到了最佳带宽、冷却时间、频谱上束流谱密度分布函数随时间的变化 ,以及在冷却过程中束流横向位移的分布等值 ,并且对功率限定情况作了讨论 ,从而为冷却系统的设计、优化。Betatron stochastic cooling will be built to cool hot beams in very short time on HIRFL-CSRm during its stripping injection. Here the transverse cooling is described and simulated. The cooling time and the beam distribution are obtained. The power-limited cooling system, which performance is limited by available output power, is contrasted with non-power-limited system and the upgrading is also mentioned. All these are useful for analysis of experimental data and for design of the cooling system and running, i.e., optimization of the system passband specification of accuracy of the signal’s transmission, etc.
