Lead-ion physics at the LHC and the SPS North Area is already under way and progressing well. The final lead-ion user in the PS East Area started its physics run on 13 November
Almost the whole accelerator complex is now in “physics mode”, routinely delivering the various types of beam to the different physics facilities and experiments. Notably, the intensity ramp-up in the LHC is progressing remarkably well
For the first time, scientists at CERN, in collaboration with scientists at GSI, have been able to measure a coupled resonance structure that may cause particle loss in accelerators
