Description
The High Energy Photon Source (HEPS), China’s first high-performance fourth-generation synchrotron radiation facility, enables exploration of microscopic material structures and serves as an advanced experimental platform for multidisciplinary research. As a critical component of HEPS, vacuum chambers require precise alignment to ensure the stability of electron beam transport, particularly under the stringent constraints of small beam apertures (1.5 mm) and long vacuum pipe lengths. With over 2,000 vacuum chambers of diverse specifications requiring alignment data, manual coordinate calculations face significant challenges in efficiency and accuracy. To address this, this study proposes a multi-method framework integrating the center-point method, vertex method, and survey-point method to rapidly generate alignment coordinates for vacuum chambers. These methods, tailored to geometric constraints, enable cross-verification of results to enhance reliability. A computational pipeline was developed to automate data processing, reducing coordinate calculation time from weeks to hours. This work establishes a scalable technical paradigm for alignment coordinate generation, offering practical guidance for precision installation in large-scale accelerator facilities.
