CERN Users' Meeting is an annual gathering that brings together scientists, engineers, administrators, and students affiliated with CERN to discuss accelerator operations, detector development, computing, and collaborative projects. The meeting routinely attracts delegates from major laboratories and institutions including Fermilab, DESY, KEK, SLAC National Accelerator Laboratory, and numerous universities across Europe and beyond. It serves as a forum for strategic planning, technical review, and community-building among users of the Large Hadron Collider, other accelerators at CERN facilities, and affiliated experiments such as ATLAS experiment, CMS experiment, ALICE, and LHCb.
The origins trace to informal user gatherings in the early decades of CERN activity, evolving through institutionalization in the 1970s and 1980s as collaborations like UA1 experiment and UA2 experiment expanded. Milestones include meetings during the construction phases of the Large Electron–Positron Collider and the Large Hadron Collider, and pivotal sessions coinciding with the discovery announcements associated with the Higgs boson by the ATLAS experiment and CMS experiment. The meeting adapted to shifts in high-energy physics priorities aligned with reports by committees such as the European Strategy for Particle Physics and the Particle Physics Project Prioritization Panel. During periods of major upgrades—like the High-Luminosity Large Hadron Collider project—the meeting played a role in coordinating users from initiatives including CERN openlab and the Worldwide LHC Computing Grid.
The event is organized by the CERN Users' Organization, with governance linked to the CERN Council and consultative input from collaborations such as ATLAS Collaboration, CMS Collaboration, and the European Physical Society where relevant. An elected committee of user representatives liaises with the Director-General of CERN and technical coordinators from laboratories like Brookhaven National Laboratory and Institute of High Energy Physics (China). Agenda-setting draws on strategic documents from the Scientific Policy Committee (CERN) and feedback from institutional members such as Imperial College London, University of Oxford, École Polytechnique Fédérale de Lausanne, and national laboratories represented in the European Research Area.
Participants comprise named scientists from legacy experiments (for example, contributors to UA1 experiment), early-career researchers from universities including University of Cambridge and Stanford University, engineers from industrial partners such as Siemens and Thales Group, and representatives of funding agencies like European Commission and national research councils including the National Science Foundation (United States). Membership categories include individual users, institutional delegates from universities and institutes like CERN Member States universities, and collaboration-appointed delegates from consortia such as LHCb Collaboration. Student outreach often involves groups affiliated with Rutherford Appleton Laboratory or summer programs like those run by CERN.
Typical programmes feature plenary addresses, parallel technical sessions, poster sessions, and working-group meetings addressing detector subsystems (for example, trackers and calorimeters developed by teams connected to ATLAS experiment), accelerator performance sessions referencing Large Hadron Collider beam parameters, and computing workshops tied to ALICE and CMS. Specialized tutorials on topics like cryogenics from Fermilab experts or data preservation with partners such as the European Grid Infrastructure are standard. Social and outreach activities include exhibition booths from instrumentation firms like Oxford Instruments and public lectures in collaboration with institutions such as the Science Museum, London.
Presentations have included technical reports on upgrades for the High-Luminosity Large Hadron Collider and milestone briefings on physics results communicated by ATLAS Collaboration and CMS Collaboration spokespersons. Outcomes have ranged from coordination agreements for detector refurbishments involving CERN and partner labs such as DESY to collaborative memoranda between academic groups at University of Pisa and industrial suppliers. Historic announcements about commissioning phases for accelerators like the Large Electron–Positron Collider and policy discussions influenced by committees such as the Scientific Policy Committee (CERN) have also been central to proceedings.
The meeting fosters cross-institutional collaborations linking universities such as University of Milan and École Normale Supérieure with national laboratories like Lawrence Berkeley National Laboratory and TRIUMF. It catalyses technical standardization for detector components used by collaborations like ALICE and LHCb and helps align computational strategies across projects including the Worldwide LHC Computing Grid and CERN openlab. Strategic dialogues held there have informed funding priorities and roadmap documents such as the European Strategy for Particle Physics and influenced multinational partnerships with agencies like the European Commission.
Held primarily on the CERN Meyrin site and associated conference facilities in Geneva, scheduling is typically annual, timed to coincide with operational cycles of accelerators such as pre-shutdown or post-run periods for the Large Hadron Collider. Remote participation has increased via platforms used by partners including Indico (software) and video links connected to institutions like ETH Zurich and University of Tokyo. Special editions have been co-located with major events at venues like the Palais des Nations in Geneva when broader diplomatic engagement with bodies such as the United Nations Office at Geneva was desirable.
