摘要
射频驱动的共振自旋旋转器是粒子与核物理极化实验中的标准仪器。在运行期间维持自旋旋转器频率与自旋进动频率相等的连续精确参数自旋共振条件是一大挑战。我们详细解析描述了偏离精确自旋共振对极化和面内进动分量所造成的影响。此处所提出形式体系的一个重要部分是考虑实验相关的自旋退相干效应。我们讨论了所发展形式体系在解释新型先导束团方法实验数据中的应用，该方法用于在 COSY 首次直接氘核电偶极矩测量中作为自旋旋转器的射频驱动 Wien 滤波器运行期间控制自旋共振条件。我们强调迄今未被探索的水平极化包络相位作为储存环中射频驱动自旋旋转稳定性指示器的潜在重要性。本文工作是同期发表的关于所谓先导束团方法原理验证实验（该方法旨在为 COSY 氘核电偶极矩实验提供共磁测量）的卫星出版物。
