摘要

瑞士光源(SLS)将于 2023 Ű24年通过更换现有大厅中的存储环进行升级。SLS 的晶格由 12 个工作在 2.4 GeV 的三弯弧形晶格组成,将被一个工作在 2.7 GeV 的 12 × 7-BA 晶格所取代,从而将硬 X 射线亮度提高 60 倍。由于现有隧道的限制,该布局的周长仅为 288 米,但利用纵向梯度和反向弯曲实现了 158 pm 的低发射率。动态孔径足够大,可以从基于 4 碰撞器的经典注入开始。此外,还实现了使用快速启动器进行同轴注入的升级路径。18 毫米内径的小横梁管和相应的磁体孔径减小,以及所有弯曲磁体均使用永久磁铁,使得晶格密集,从而将设备的总功耗降低了 30%。

SLS 2.0 – The Upgrade of the Swiss Light Source
The Swiss Light Source (SLS) will be upgraded by replacing the storage ring in the existing hall in 2023Ű24. The SLS lattice build from 12 triple-bend arcs operating at 2.4 GeV is replaced by a 12 × 7-BA lattice operating at 2.7 GeV to increase hard X-ray brightness by a factor 60. The layout is constrained by the existing tunnel to 288 m circumference, nevertheless a low emittance of 158 pm is realized using longitudinal gradient and reverse bends. Dynamic aperture is suicient to start with classical injection based on a 4-kicker bump. An upgrade path for on-axis injection with fast kickers has been implemented. Small beam pipes of 18 mm inner diameter and corresponding reduction of magnet bores, and the use of permanent magnets for all bending magnets enables a densely packed lattice and contributes most to a reduction of total power consumption of the facility by 30%.
