The European Synchrotron Radiation Facility (ESRF) Extremely Brilliant Source (EBS) was installed in 2019 and commissioned in 2020. The alignment tolerances for the most demanding magnets—including the combined-function magnets, high-gradient quadrupoles, and sextupoles—were approximately 60 µm (2.5σ).
Between 2019 and 2025, no global realignment of the Storage Ring (SR) was made. During...

The European Synchrotron Radiation Facility (ESRF) operates a well-established program of comprehensive Storage Ring (SR) and regular machine surveys to maintain the geometric integrity of the accelerator and serve as the primary reference for all beamlines. Over the past three decades, the SR survey has evolved into a highly coordinated activity comprising nearly 10,000 measurements completed...

The Survey and Alignment Group measures its primary network of reference points through a full survey managed every six months. This survey consists of nearly 9,000 measurements acquired using laser tracker-based tacheometry and direct leveling with digital levels. It is carried out during the first week of each semi-annual machine shutdown and involves between one and four teams working...
