First images of collisions at 13 TeV

Geneva, 21 May 2015. Last night, protons collided in the Large Hadron Collider (LHC) at the record-breaking energy of 13 TeV for the first time. These test collisions were to set up systems that protect the machine and detectors from particles that stray from the edges of the beam.

A key part of the process was the set-up of the collimators. These devices which absorb stray particles were adjusted in colliding-beam conditions. This set-up will give the accelerator team the data they need to ensure that the LHC magnets and detectors are fully protected.

LHC restart update

After a shutdown lasting two years, the Large Hadron Collider (LHC), the world’s biggest and most powerful particle accelerator, is ready once again for the arrival of particle beams. The teams are completing the final tests after having solved on 31 March the problem that had been delaying the restart of the accelerator. The first beams could be circulating in the machine sometime between Saturday and Monday.
