结果显示，新的控制方法对强流加速器中5种初始分布的离子束均有较好的控制效果。 - The button electrode is one that widely used in high energy rf accelerators , such as storage ring , and the bpm made of button electrodes has many merits like high accuracy , high resolution , resisting magnetic field , simple machinery , without magnetic core and low cost , etc . so we want to use the button electrode as the bpm in high current accelerators like the lia
钮扣电极束位置探测器是一种广泛应用于射频加速器储存环等高能弱流加速器的一种束位置测量装置，它具有测量精度高、分辨率高、不受磁场干扰、机械结构简单、无磁芯、造价低廉等特点。只是，至今未见有关这种束位置探测器在强流加速器(如，直线感应加速器)上应用的报导，如能将钮扣电极束位置探测器应用于lia ，将是一件很有意义的事情。 - The control of beam halo - chaos becomes a critical problem in the development of high intensity accelerator . efforts to remove the halo by collimation have been largely unsuccessful since the halos almost always regenerate . the mechanisms of halos are complex , such as nonlinear resonances and chaotic behavior etc . considering this , professor fang jin - qing who works in china institute of atomic energy pointed out that the theory of chaos control can be used to control beam halos . he presented the method to control halos by using nonlinear functions , which means nonlinear function g is added to the right of ion radial self - edlctric force equation and some nonlinear function are selected to control beam halos in simulations . in paper [ 69 ] , controllerg = - 0 . 15sin ( rmax - am ) 2 was used and the halo intensity was decreased to 0 . 1078 , the halos are removed partly
束晕?混沌的控制是新一代强流加速器研制的关键问题，随着强流离子束应用前景的日趋广阔而日益成为研究的热点。传统机械限束器因无法解决束晕的再生而收效甚微，因为束晕的形成有着其内在动力学机制?非线性共振以及混沌等。基于此，中国原子能科学院研究员方锦清将混沌控制的理论和方法开创性的运用于束晕?混沌的控制上，提出了控制束晕?混沌的非线性控制策略，即在粒子径向所受束自生场力方程的右边加上非线性控制函数g ：并选取一些非线性函数如等进行了控制的模拟研究，将束晕强度控制在0 . 1078左右，取得了初步的控制效果。 - In this paper , we give a summary of controlling chaos and a review of the mechanism of beam halo and its nonlinear control . then delayed self - controlling feedback method is presented to control beam halo - chaos . this method , not only can control beam halo - chaos well , but also is easy to work out because of the linearity and the simpleness of its controller . considering the advantage in technology realizing and cost saving , this method is recommended to the development of high intensity accelerator
本文在综述混沌控制和回顾束晕?混沌形成机制及其非线性控制的基础上，提出了应用延迟反馈控制束晕?混沌的方法。该法不仅控制效果显著，而且由于采用线性控制律，控制器形式简单，施加的反馈较小，因此该法非常有利于工程技术实现和降低控制代价，可为实用强流加速器的研制提供有价值的参考。
