| 摘 要： | 描述了一台低能电子储存环的lattice设计，包括线性光学参数设计和非线性动力学孔径优化．该储存环有两种运行模式，在低发射度模式下柬流发射度接近软X射线衍射限制发射度，光源亮度远高于合肥光源，同时用于安装插入元件的直线节数目较多；在等时性模式下线性动量紧缩因子连续可调，能够较方便地调节束团长度．

| Abstract: | The lattice design for a low energy electron storage ring was described in detail, including linear optical parameters and nonlinear dynamic aperture. There are two operation mode of this ring. First, with low emittance lattice configuration, beam emittance can be decreased approaching the diffraction limit of soft X-ray, which is very helpful to enhance brilliance, aiid the number of straight section for insertion device is greater than that of current Hefei light source. Secondly, with isochronous mode, the momentum compaction factor can be varied continuously, which is essential for bunch length adjustment. |
