@cern.official: What’s going on at the #LHC? 🤔 While the Large Hadron Collider mostly collides protons, once a year it collides heavy ions – such as lead nuclei – a key ingredient for recreating the extreme conditions of the early #Universe. Hear from Silvia Pisano, Run Coordinator at the ALICE Experiment, about this year’s heavy-ion run at the LHC, and what’s happening after it. The run will conclude with a two-week high-intensity test, which will probe the LHC’s behaviour under conditions closer to those expected at the #HiLumiLHC. #AskAPhysicist #LHCRun3
