论文摘要
对于现代的高强度线性加速器，众所周知的包膜不稳定性和最近报道的四阶粒子共振施加了基本的操作极限（即零流动相位的前进应小于90度）。通过旋转飞行对象的稳定性的激励，我们提出了一种新的方法，即使用旋转光束超过此极限。我们发现旋转梁具有固有的特征，可以抑制四阶共振对发射量生长和相关的包膜不稳定性的影响。
For modern high-intensity linear accelerators, the well-known envelope instability and recently reported fourth-order particle resonance impose a fundamental operational limit (i.e., zero-current phase advance should be less than 90 deg). Motivated by the stability of spinning flying objects, we propose a novel approach of using spinning beams to surpass this limit. We discovered that spinning beams have an intrinsic characteristic that can suppress the impact of the fourth-order resonance on emittance growth and the associated envelope instability.
