介绍了HIRFL-CSR调试的主要成果和冷却器的主要参数。借助电子冷却程序，分别对HIRFL-CSR电子冷却储存环中不同束流参数（如束流能量、初始横向发射度、动量散布）下的离子束冷却时间进行了广泛的模拟。研究了机器晶格参数-电子感应加速器函数和色散函数对冷却时间的影响。计算中考虑了有效冷却长度、冷却段磁场强度及其平行度、电子束尺寸和束流密度等电子束参数和冷却装置参数。结果表明，HIRFL-CSR的晶格参数对电子冷却是最佳的，电子束流参数可以根据重离子束流参数进行优化。
The brief achievements of HIRFL‐CSR commissioning and the achieved parameters of its coolers were presented. With the help of electron cooling code, the cooling time of ion beam were extensive simulated in various parameters of the ion beam in the HIRFL‐CSR electron cooling storage rings respectively, such as ion beam energy, initial transverse emittance, and momentum spread. The influence of the machine lattice parameters‐betatron function, and dispersion function on the cooling time was investigated. The parameters of electron beam and cooling devices were taken into account, such as effective cooling length, magnetic field strength and its parallelism in cooling section, electron beam size and density. As a result, the lattice parameters of HIRFL‐CSR were optimal for electron cooling, and the parameters of electron beam can be optimized according to the parameters of heavy ion beam.
