Beam Manipulation and nonlinear beam dynamics studies

该提议旨在研究与理解储存环中的非线性粒子运动有关的束流动力学问题。这些研究课题对于利用高亮度粒子束进行核物理研究是不可或缺的。本研究对加速器物理研究生和本科生的培养也具有重要意义。在过去的几年里，IUCF冷却环已经成为研究非线性束流动力学的世界领先实验室。更重要的是，冷却器环束动力学实验的结果被用来理解混沌、奇异和极限环吸引子以及吸引子的分叉特性等现象。我们的实验结果已被用于改善冷却光束质量，为高能对撞机电源波纹的设计提供依据，并为高亮度光束的发射度保持提供新的方法。高亮度光束的一些应用包括介子工厂、散裂中子源、重离子聚变、生物化学和生物医学、材料科学和国防研究。

9876773Lee The proposal is intended to investigate beam dynamics problems relevant to the understanding of the nonlinear particle motion in storage rings. These proposed research topics are indispensable to nuclear physics research using high brightness particle beams. The proposed research is also important in training accelerator physics graduate and undergraduate students. In past few years, the IUCF Cooler Ring has become the world leading laboratory for nonlinear beam dynamics research. More importantly, results of the Cooler Ring beam dynamics experiments have been employed to understand phenomena such as chaos, strange and limiting cycle attractors, and bifurcation characteristics of attractors. Our experimental results have been used to improve Cooler beam quality, to provide design criterion for power supply ripple in high energy colliders, and to develope new methods for emittance preservation of high brightness beams. Some applications of high brightness beams are meson factories, spallation neutron sources, heavy ion fusion, biochemistry and bio-medical, material science, and defense research.
