储存环上的放射性核束流品质计算

为给兰州重离子加速器冷却储存环（ＨＩＲＦＬ－ＣＳＲ）注入放射性核束（ＲＩＢ）提供初始参数，及为ＣＳＲ上ＲＩＢ分离谱仪的物理设计提供依据，对最近几年发展起来的利用弹核碎裂（ＰＦ）、双消色散分离谱仪在线获取和分离所需ＲＩＢ的参数计算方法，进行了系统的总结；给设计中的ＣＳＲ－ＲＩＢ分离谱仪设定一组束流光学参数，在此基础上对一组具有代表性的反应道的部分参数进行了初步计算，并用ＧＡＮＩＬ发展的相关程序ＬＩＳＥ进行了验证．理论与实验均表明，在目前对ＰＦ反应机制尚不能精确描述的情况下，对ＲＩＢ产额的计算结果达到１～２数量级的精度；对ＲＩＢ横向发射度和动量散度的计算结果相对准确. The calculation of the parameters of RIB produced by the projectile fragmentation and separated by an achromatic spectrometer is firstly summarized. The calculation method to the RSPC(the RIB spectrometer between CSR main ring and the experimental ring) is then described. The final results of the yield, the energy spread and the transversal emittance of some typical RIB has been obtained.

Analysis and implementation of new fractional-order multi-scroll hidden attractors

To improve the complexity of chaotic signals,in this paper we first put forward a new three-dimensional quadratic fractional-order multi-scroll hidden chaotic system,then we use the Adomian decomposition algorithm to solve the proposed fractional-order chaotic system and obtain the chaotic phase diagrams of different orders,as well as the Lyaponov exponent spectrum,bifurcation diagram,and SE complexity of the 0.99-order system.In the process of analyzing the system,we find that the system possesses the dynamic behaviors of hidden attractors and hidden bifurcations.Next,we also propose a method of using the Lyapunov exponents to describe the basins of attraction of the chaotic system in the matlab environment for the first time,and obtain the basins of attraction under different order conditions.Finally,we construct an analog circuit system of the fractional-order chaotic system by using an equivalent circuit module of the fractional-order integral operators,thus realizing the 0.9-order multi-scroll hidden chaotic attractors.
