储存环中横向和纵向相空间随机冷却的二维计算

2D CALCULATION OF TRANSVERSE AND LONGITUDINALPHASE SPACE STOCHASTIC COOLING IN A STORAGE RING

对兰州重离子冷却储存环ＨＩＲＦＬ－ＣＳＲ的随机冷却装置进行了设计。基于Ｆｏｋｋｅｒ－Ｐｌａｎｃｋ方程，对陷波器方式纵向冷却及横向冷却时间作了二维计算，在计算过程中，得到并使用了冷却最快的增益曲线。

A stochastic cooling system was designed in the HIRFLCSR project. Based on FokkerPlanck equation, the cooling time of the longitudinal cooling with a notch filter and transverse cooling was calculated. During the calculation, the optimum gain was obtained and applied.
