论文摘要
垂直电场需要保持比储物环电偶极矩实验中的水平电场小的数量级。否则，与磁偶极矩的耦合主导了自旋进动，最终导致了错误的信号。这项工作介绍了有关静电四极特谱优化的首次定量研究，这有助于抑制图像光束诱导的垂直电场。除了表现出轮廓优化的演示外，还研究了其抑制性能，以进行各种光束偏移和光束尺寸配置。发现有了最佳剖面，垂直电场可以减少两个数量级。
Vertical electric fields need to remain orders of magnitude smaller than the horizontal electric field in storage ring electric dipole moment experiments. Otherwise, the coupling with the magnetic dipole moment dominates the spin precession, eventually leading to a false signal. This work presents first quantitative studies regarding electrostatic quadrupole profile optimization, which helps suppressing image beam induced vertical electric fields. Besides the demonstration of the profile optimization, its suppression performance is also studied for various beam offsets and beam size configurations. It is found that with the optimum profile, the vertical electric field can be reduced by two orders of magnitude.
