Nikhef Summer Series on the upgraded CERN accelerator: the HiLumi LHC project

10 August 2026

In a new summer series, Nikhef will present weekly stories about the work planned for the coming years to make the LHC accelerator at CERN even more effective. The HiLumi LHC is scheduled to go into operation in 2030, opening a new chapter in particle physics research.

Earlier this summer, the existing LHC accelerator at CERN shut down after years of service to undergo a major overhaul. In three years, the High Luminosity LHC is set to become a reality—a proton accelerator based on the LHC that will deliver ten times as many collisions into the detectors.

The more powerful accelerator will thus become a “Higgs factory,” producing Higgs particles on a massive scale for precision research into the particle discovered in 2012. In addition, the abundance of collisions may provide insight into rare processes and interactions, forming the basis for systematic research.

The summer series consists of four stories. The first part  covers the major modifications that will be made to the CERN accelerator. Part two gives an overview of the physics that the upgraded accelerator is expected to yield. The third part focuses on Nikhef’s work in connection with the arrival of the HiLumi LHC. And part four highlights the HiLumi related efforts in the field of data processing. The fifth episode is about the computers and networks that need to keep up with the data.

Episodes of the summer series will be published weekly on Fridays on Nikhef’s website and social media, starting August 14.
