What’s new at CERN? Towards High-Luminosity at the Large Hadron Collider


27.06.2017 - 13:30 to 14:00




To extend its discovery potential, CERN’s Large Hadron Collider will undergo a massive upgrade within the next 10 years, to become the High-Luminosity LHC, in order to increase our understanding at the energy frontier. 

Luminosity is a parameter indicating the number of particles colliding within a defined amount of time. The peak luminosity of the LHC is planned to be increased  by a factor of five by 2025. This will make it possible for the experiments to record about 10 times more data over the period 2025 to 2035 than all what will have been accumulated before.

The High-Luminosity LHC will therefore provide more accurate measurements of fundamental particles than today – including the famous Higgs boson - as well as the possibility of observing rare processes that occur beyond the machine’s present sensitivity level. For example, the High-Luminosity LHC will produce 15 million Higgs bosons per year compared to the 1.2 million in total created at the LHC between 2011 and 2012.

As the work towards this important upgrade is just starting, this press briefing will present an overview of the High-Luminosity LHC, as well as the key challenges and innovative technologies that will keep the LHC at the forefront of research for the next 20 years.

Speaker: Frédérick Bordry, CERN Director for Accelerators and Technology.
