The collimation system of the Large Hadron Collider (LHC), which protects the accelerator’s components, needs an upgrade to be able to handle the performance of CERN’s future accelerator

Watch CERN engineers explain the work during the laboratory's long shutdown to prepare the LHC for running at 13 TeV

With ‘LHC Season 2’ starting soon, running at a new high energy, the LHC key is handed back to the machine operators today

Weekend tests with beams brought protons just short of the LHC

On Wednesday, 10 September, the last NA62 straw tracker chamber was lowered into position in the experiment

Experiments in the East Area received their first beams from the PS last week. Theirs is CERN's first accelerator-based physics since LS1 began

Cool down of the Large Hadron Collider has already begun in preparation for research to resume early in 2015

On 2 June the PS Booster had beam for the first time since the beginning of LS1

Images of the last of over ten thousand M welds on LHC magnet interconnections that were performed as part of the LS1 consolidation work

With Linac2 up and running, the countdown to beam in the LHC has begun: next in line is the PS Booster

With the pressure tests now complete we are coming to the equally important phase of cleaning the machine

Last week several CERN teams were involved in creating a life-size mock helium leak in Sector 4-5
