论文摘要
旨在测量带电颗粒的电偶极矩（EDM）的建议需要充分了解系统的误差，这可能有助于模仿要检测到的EDM信号的垂直自旋堆积。在接下来的内容中，采用了一种从Bogoliubov-Krylov Mitropolski方法进行平均的方法来求解T-BMT方程并计算用于储存环冷冻旋转概念的浆果相。事实证明，所采用的形式主义对于确定观测点的自旋的演变特别有用，即在偏振仪的位置。模拟了几个选定的晶格缺陷案例，并通过分析估计值进行基准测试。这允许证明数值模拟的收敛性，并有助于更好地了解系统错误。
Proposals aimed at measuring the Electric Dipole Moment (EDM) for charged particles require a good understanding of the systematic errors that can contribute to a vertical spin buildup mimicking the EDM signal to be detected. In what follows, a method of averaging emanating from the Bogoliubov-Krylov Mitropolski method is employed to solve the T-BMT equation and calculate the Berry phases arising for the storage ring frozen spin concept. The formalism employed proved to be particularly useful to determine the evolution of the spin at the observation point, i.e. at the location of the polarimeter. Several selected cases of lattice imperfections were simulated and benchmarked with the analytical estimates. This allowed the proof of the convergence of the numerical simulations and helped gain better understanding of the systematic errors.
