COSY EDM实验的自旋动力学研究

Spin dynamics investigations for the EDM experiment at COSY

F. Rathmann, N. N. Nikolaev, J. Slim

摘要:

精确的实验,例如使用COSY这样的储存环寻找氘核电偶极矩,需要以前所未有的精度理解自旋动力学。在这样的企业中,数值预测对自旋跟踪算法的开发和后来的应用起着至关重要的作用。讨论了COSY中由RF Wien滤波器和静态极化引起的各种测量概念。这里应用的矩阵形式主义将\textit{solely}与机器的自旋旋转\textit{on the closed orbit}进行处理,并且旨在为环的束和自旋跟踪代码的开发提供\textit{numerical}指导,所述环采用对电和磁弯曲和聚焦元件等的真实描述,和一个真实建模的RF维恩滤波器。

英文摘要:

Precision experiments, such as the search for a deuteron electric dipole moments using a storage rings like COSY, demand for an understanding of the spin dynamics with unprecedented accuracy. In such an enterprise, numerical predictions play a crucial role for the development and later application of spin-tracking algorithms. Various measurement concepts involving polarization effects induced by an RF Wien filter and static solenoids in COSY are discussed. The matrix formalism, applied here, deals \textit{solely} with spin rotations \textit{on the closed orbit} of the machine, and is intended to provide \textit{numerical} guidance for the development of beam and spin-tracking codes for rings that employ realistic descriptions of the electric and magnetic bending and focusing elements, solenoids etc., and a realistically-modeled RF Wien filter.
