北京τ─粲工厂储存环磁聚焦结构的设计研究

Study of the Lattice Design of BTCF Storage Ring

对北京τ－粲工厂（BTCF）储存环磁聚焦结构设计中所涉及的一些关键物理问题作了探讨和研究，提出了可行性的方案．该方案的高亮度模式动力学孔径较大；单色模式的托歇克寿命较长、亮度较高；并且能兼容纵向极化束对撞模式．

The physics issues involved in the lattice design of Beijing Tau-charm Factory (BTCF) storage ring are investigated and studied. A lattice that takes the high luminosity mode as the first priority and is compatible with monochromator mode and polarized beam collision mode is proposed. It's a feasible design with large dynamic aperture for the high luminosity mode and acceptable Touschek lifetime for the monochromator mode.
