采用来自局部区域内的控制信息和对数函数控制器对初始分布为K—V分布的离子束进行束晕-混沌的模拟控制。结果显示,用局部区域内的离子数作为控制信息的对数函数控制法能够有效的抑制束晕-混沌的再生,控制效果不亚于其他控制方法,而且由于该控制信息来源区域很小,具有在实验上实施定点探测的优点,要远远优于其他控制方法。
A simulation study on high intensity ion beams which exhibits a Kapchinskij-Vladimirskij(K- V)distribution by the information from the particles in small region of the beam and the logarithmfunction controller is adopted. It shows the controlling information can control the beam halo-chaos effectively, and its result is as good as other controller. The source region of controlling information is smaller than that of other controlling methods, so the method is excel to other controller.
