CERN – extension particle accelerator

Geneva, Switzerland

The Large Hadron Collider (LHC) at the European nuclear re­search center CERN in Geneva is the world’s largest particle ac­celer­ator. Back in 2018, CERN launched the High Luminosity (HiLu) project, with the ob­jecti­ve of vastly ex­panding the LHC’s cap­abilities. The particle ac­celer­ator was shut down while Marti was tackling part of this ex­pansion. In April 2022, how­ever, protons were al­ready racing around the ring again.
