3 Jun 2025, 17:30 → 5 Jun 2025, 16:30 Europe/Zurich

 The third European Workshop on Accelerator Alignment will take place at the ESRF from June 3 to 6, 2025, following successful workshops in June 2023 and April 2024 at the ESRF and CERN. The workshop aims to promote information exchange and build a stron European community focused on Accelerator, Detector, and Beamline Alignment. Key topics will include instruments, measurement techniques, uncertainty analysis, the Engineering to Alignment (E2A) worklow, software, artificial intelligence, machine learning, and worforce-related challenges.
