摘　　要：考虑储存环内离子的横向振荡和纵向振荡的运动特性，模拟了ＨＩＲＦＬ－ＣＳＲ内重离子束的电子冷却过程．给出了离子束的横向发射度和纵向动量散度随时间连续变化的图象，由此分析了电子束的空间电荷效应。A simulation of electron cooling process for the heavy ion beam in the proposed HIRFL Cooler Storage Ring(HIRFL CSR)is performed by taking into account the betatron and synchrotron oscillations of single particle.The continuous evolution of ion beam emittances and relative momentum spread are shown.Some factors that influence the cooling speed,like the space charge effect of electron beam,the dispersion in cooler section and the electron beam transverse temperature are presented.
