【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6 T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。更多还原

【Abstract】 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 and β 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 and β function distortion,then the beam lifetime was improved significantly.更多还原
