Today, the world’s most powerful particle accelerator, the Large Hadron Collider (LHC), begins Run 3, a new period of data taking! This comes after more than three years of upgrade and maintenance work.

ESnet is looking forward to continuing to support the US LHC community for Run 3 through its connectivity to CERN. ESnet carries all traffic for LHC from Europe to the US, to the two Tier 1 centers at Fermilab and Brookhaven National Lab, and for all the physicists in Tier 2 centers in Universities. You can see the list of LHCONE collaborators at
