The first beams could be circulating in the machine sometime between Saturday and Monday
The short circuit to ground delaying the restart of the LHC has been fixed
Against a backdrop of great progress in the powering tests for running at 6.5 TeV, a short cicuit is causing a delay, writes Rolf Heuer
A short circuit in a superconducting dipole magnet is delaying the beam injection in the LHC. Teams are working around the clock to fix the issue
LHC run 2 is coming ever closer, but there will be no beam in the LHC this week
This week delegates at the first Annual Meeting of the FCC study will discuss the status of their project to decide on a baseline for further study
This week saw the cost and schedule of the High Luminosity LHC (HL-LHC) and LHC Injectors Upgrade (LIU) projects come under close scrutiny
Today the ATLAS and CMS experiments presented for the first time a combination of their results on the mass of the Higgs boson
Work continues apace for the high-luminosity upgrade for the LHC 10 years from now
Watch CERN engineers explain the work during the laboratory's long shutdown to prepare the LHC for running at 13 TeV
Particles were successfully injected into the LHC last weekend, passing through three sectors of the accelerator
The Operations team is testing the systems that deliver beams to the Large Hadron Collider in preparation for the start-up this month
