摘要

摘要同步加速器 "准冻结 "自旋模式的一个显著特点是在直线部分安装了具有交叉磁场和电场的特殊元件，以补偿弧线上 MDM 分量产生的自旋旋转。此外，由于光束内部存在纵向长度和动量扩散，自旋旋转可能会不连贯地发生。为了抑制这种效应，安装了六极点，这也会影响色度的抑制。

Spin Coherence and Betatron Chromaticity of Deuteron Beam in “Quasi-Frozen” Spin Regime

A distinctive feature of the “quasi-frozen” spin mode in the synchrotron is the installation of special elements with crossed magnetic and electric fields in straight sections that compensate the spin rotation from the MDM components on the arcs. Moreover, because of the presence of the longitudinal length and the momentum spread inside the beam, spin rotation may occur incoherently. In order to suppress this effect, sextupoles are installed, which also affect suppression of chromaticity.

期刊介绍： Physics of Atomic Nuclei is a journal that covers experimental and theoretical studies of nuclear physics: nuclear structure, spectra, and properties; radiation, fission, and nuclear reactions induced by photons, leptons, hadrons, and nuclei; fundamental interactions and symmetries; hadrons (with light, strange, charm, and bottom quarks); particle collisions at high and superhigh energies; gauge and unified quantum field theories, quark models, supersymmetry and supergravity, astrophysics and cosmology.
