中文摘要：

合肥光源是1台专用真空紫外光源，为拓展同步辐射用户可用光范围，在储存环上安装了1台6T的超导扭摆磁铁。超导扭摆磁铁给储存环光学参数带来很大扰动，造成工作点漂移和β函数畸变。最初，在补偿工作点漂移后，成功地存储了束流并产生了硬X射线，但该运行模式下束流寿命短，严重影响其它实验线站的实验工作。在合肥光源二期工程中，重新进行了超导扭摆磁铁补偿计算，在不改变目前储存环磁铁和电源的基础上，同时补偿工作点漂移和β函数畸变，大幅度地改善了束流寿命。

英文摘要：

Hefei light source（HLS） is a dedicated VUV light source. A superconducting （SC） wiggler magnet with peak magnetic field of 6 T was installed in the storage ring in order to extend usable synchrotron radiation spectrum to hard X-ray. The SC wiggler brought a large perturbation to optical parameters of the storage ring, including tune shift andβ function distortion. At early days, after tune compensation with SC wiggler, beam was successfully stored with a short beam lifetime. In phase Ⅱ project of HLS, the lattice parameters were adjusted to compensate tune shift andβ function distortion, then the beam lifetime was improved significantly.
