AI 中文摘要
在费米实验室可积光学测试加速器上对二维非线性可积系统进行了实验演示。该系统通过在传统加速器晶格中插入特殊非线性磁体实现。通过测量150 MeV电子束的寿命、横向分布和横向振荡频率随非线性插入强度的变化来表征系统。测量的工作点偏移和幅度相关失谐与理论预测一致，还观察到稳定闭合轨道的预测分岔。该系统实现的一个显著结果是储存环可在整数调谐下运行而不降低寿命。这项研究为设计粒子加速器和稳定粒子束开辟了新途径。
英文摘要
A two-dimensional nonlinear integrable system was experimentally demonstrated at the Fermilab Integrable Optics Test Accelerator. The system was implemented by inserting a special nonlinear magnet in a conventional accelerator lattice. We characterized the system by measuring lifetimes, transverse profiles and transverse oscillation frequencies of the 150-MeV electron beam as a function of the strength of the nonlinear insert. The measured shift of the working point and the amplitude-dependent detuning were consistent with theoretical predictions. We also observed the predicted bifurcation of the stable closed orbit. A striking consequence of the system's implementation was the possibility to operate the storage ring with integer tunes without lifetime degradation. This research opens up novel ways to design particle accelerators and to stabilize particle beams.
