Worldwide Collaboration

The High-Luminosity LHC is a worldwide collaboration, with collaborative partners in Europe and further afield contributing key technologies for the upgrade. The project relies not only on the success and bringing together of many technologies, but also on collaborative effort, with each person at CERN and the collaborating institutes bringing their own unique expertise.

Project members from across the collaboration reflect on over a decade of work in the HiLumi LHC project.
