Description
Layout design is a core procedure in particle accelerator development, which guarantees the precise implementation of physics design and underpins full-lifecycle operation and maintenance of the facilities. 2D layout drawings act as fundamental engineering benchmarks for equipment positioning, while 3D layout models provide a global spatial perspective for coordination verification and construction guidance.
Next-generation large-scale scientific facilities, represented by the High Energy Photon Source (HEPS) and the Circular Electron-Positron Collider (CEPC), are evolving toward compact designs with sub-millimeter positioning accuracy. This trend leads to exponential growth in equipment quantity and layout complexity. Nevertheless, the traditional phased manual iteration workflow for layout design has shown critical bottlenecks: isolated 2D and 3D data systems, dependence on manual cross-dimension updates, heavy repetitive workload, and error accumulation during version iterations. These drawbacks make it difficult to meet the high-efficiency design requirements of future ultra-large accelerator facilities.
To address the above issues, this paper proposes a 2D-3D collaborative layout design method. A parametric association model is established to realize bidirectional automatic synchronous updates between 2D and 3D layout deliverables. Furthermore, an intelligent layout algorithm based on physics survey data will be developed, which can automatically identify equipment boundary constraints, achieve accurate device positioning, and synchronously generate 2D and 3D layouts conforming to engineering specifications.
Preliminary verification based on the CEPC booster layout shows that the proposed method reduces manual repetitive drafting work by over 40%, shortens the layout design cycle by more than 30%, and effectively reduces the time cost and human error risk caused by manual operations. This study notably improves the efficiency and accuracy of accelerator layout design, and provides a replicable technical solution for the efficient design and digital upgrading of new-generation large-scale scientific facilities.
