摘要
本文展示了成功将相位锁反馈系统应用于维持射频 (rf) 自旋旋转器（具体为rf Wien 滤波器）与 120 kHz 自旋预cession 共振的条件。通过实时监控自旋预cession 和 rf Wien 滤波器信号，可以将两者之间的相对相位稳定在任意设定值。反馈系统通过必要时调整频率和/或相位来补偿相对相位的偏差。通过此方法，可实现相位相对于需求相位的标准偏差为 。该系统在旨在于2018年和2021年进行首次直接测量 deuteron 电偶极矩的两个运行中实现。此外，讨论了受自旋旋转器影响的单束流与仅一束流暴露于自旋旋转器场的两束系统之间的差异。两种方法在这些束流时间中均已使用。保持自旋预cession 与 rf 场同步的能力也对于未来使用储存环研究带电粒子电偶极矩的调查至关重要。
