Description
The Advanced Light Source Upgrade (ALS-U) is an ongoing project at Berkeley Lab to transform the ALS into a fourth-generation synchrotron light source. To minimize the ALS dark time, the ALS-U Storage Ring (SR) is composed of 48 unique, highly integrated modules, each containing approximately 35 groups of interfaces internal to the module, and 26 groups of interfaces between the modules and facilities and beamlines, totaling approximately 3000 interfaces across the SR. This contribution presents how the complex interfaces have been managed using interface control documentation and tailored interface verification methods based on a combination of CAD assemblies and dedicated prototypes. These tools were adopted to manage both module-level integration and external interfaces with facility infrastructure and beamlines. To validate the design solutions a physical 1:1 mock-up has been employed alongside the CAD models. The combined CAD-mockup validation approach revealed critical issues not detectable through CAD, including cables’ installation feasibility problems that would have caused redesign work and significant delays. The physical mockup also enabled more accurate analysis of maintenance access, assembly process and electrical safety. The practical experience from SR modules design in facility/beamlines integration context, methodology evolution during the design process, and recommendations for similar accelerator upgrade projects are also presented.
