2022: LHC restart, Run 3 and Higgs10

In 2022, CERN is restarting the LHC after more than three years of maintenance and upgrades, known as Long Shutdown 2 (LS2). Once restarted, the energy will climb to world-record levels as CERN begins LHC Run 3 for physics research. Then 4 July will mark #Higgs10, the 10th anniversary of the discovery of the Higgs boson.

Resources for journalists for these key milestones will be added below as the year progresses.


The backgrounders linked below summarise the key upgrades to the accelerators and four main LHC experiments during Long Shutdown (LS2), which began in December 2018 and runs until the LHC restarts in 2022.
