 High Luminosity Large Hadron Collider

The High Luminosity Large Hadron Collider (HL-LHC) is an upgrade project for the Large Hadron Collider (LHC), the world's largest and most powerful particle accelerator, located at CERN (the European Organization for Nuclear Research) near Geneva, Switzerland. The HL-LHC is designed to significantly enhance the LHC's luminosity, which is a measure of the collision rate of particles within the accelerator.
