【摘要】 <正> 一、同步辐射光源的结构参数设计中要求同步辐射光源具有下列特点:(1)光源的发射度小;(2)电子束的贮存时间长;(3) 动量色散函数在直线节上等于零,以便减少磁插入元件对设计特性的影响。图6中给出贮存环的结构概貌,它由四个超周期组成,每个包括两个45°的二极铁和六个四极铁,形成一个稳定的聚焦单元。注入系统由三个冲击磁铁和一个带切割片的偏转磁铁组成,偏转磁铁的出口处在直线节的中央,正对着的一个直线节安装高频谐振腔。更多还原

【Abstract】 A design study of a 600MeV synchrotron radiation light source is given inthis paper. Lattice cells of this facility are symmetrically disposed in four super-periods, momentun dispersion function equals zero in straight section. Touscheklifetime at 300mA is as long as 4 hours because of large overvoltage factor.Injection energy is 100MeV, "Multiturn" technique will be applied in injectionscheme with the help of 3 kickers and a deflecting magnet. The magnetic fieldstrengths of the kickers are in the range of tens of gauss, which can be easilyexcited by one turn coil in vacuum chamber. About 4--5 turns of electron beamcan be injected into oscillating orbit in a single pulse duration.更多还原
