Proton-ion operation has become routine for the LHC operation crew with all seven LHC experiments simultaneously taking data for first time
The LHC starts the New Year facing a new challenge: proton-lead collisions in the last month before the shutdown in mid-February
Applications to the 2013 school, which will be held in Hungary, are open until 22 February
The school, on the theme "Mastering State-of-the-Art Computing", will will take place from 3-7 June 2013 in Split, Croatia
Record number of 2,748 proton bunches injected into the LHC giving a record beam intensity of around 2.7 x 10^14 protons in both beams
Remarkable first three-year LHC run crowned by a new performance milestone
Today in the CERN auditorium teams from the LHC and its experiments will present the current status of the accelerator and detectors
Seven leaders of the LHC, CMS and ATLAS projects will share a $3m prize for advancing knowledge of the universe
A 2-day workshop is bringing together CERN researchers and companies developing innovative superconducting technologies
The last couple of weeks have seen a mixed bag of special runs, luminosity production, machine development and down-time
