论文摘要
在本文中，我们介绍了与局部螃蟹交叉方案的撞机相互作用点（IP）的线性横向纵向耦合的影响，当时间依赖于时间依赖的横向偏转（螃蟹踢）和IP附近的分散轨道Intertwine时。得出了螃蟹分散和动量分散体的分析传播公式和封闭的轨道形式。蟹腔的非零动量分散体和从螃蟹腔到IP的非理想相的非理想相详细介绍了衍生的繁殖公式，以预测具有或没有束束相互作用的IP处的梁尺寸失真。将线性结果与非线性模拟使用弱 - 丝束梁代码进行了比较。
In this paper, we present the effects of linear transverse-longitudinal coupling on beam size at Interaction Point (IP) of a collider with local crab crossing scheme, when time dependent transverse deflection (crab kicks) and dispersive orbit intertwine near IP. The analytic propagation formula and the closed orbit form of the crab dispersion and momentum dispersion are derived. The non-zero momentum dispersion at crab cavities and the non-ideal phase from crab cavities to IP are detailed with the derived propagation formula to predict the beam size distortion at IP with or without the beam-beam interaction. The linear results are compared with nonlinear simulation using the weak-strong beam-beam code.
