Every two weeks, ion-source physicist Detlef Küchler refills the lead source for the LHC with pure lead 208

The ALICE experiment will be watching the collisions closely to tease out the effects of lead ions from the effects of the plasma

Accelerator team declares "stable beams" as lead ions collide with protons in first LHC physics beams of 2013

Preparations have been progressing steadily at CMS to receive collisions between protons and lead ions

For the last run before the two-year shutdown, the LHC is going beyond its original design specification and will collide protons with lead ions

Remarkable first three-year LHC run crowned by a new performance milestone

Remarkable first three-year run of LHC comes to an end, marked by the LHC controllers with a Douglas Adams reference

Remarkable first three-year run of the world’s most powerful particle accelerator crowned by a new performance milestone

Highlights included sensitive searches for new physics, the decay of a Bs meson, quark-gluon plasma and insights on the structure of the proton

Today in the CERN auditorium teams from the LHC and its experiments will present the current status of the accelerator and detectors
