Early tomorrow morning Geneva time, the CERN Large Hadron Collider will attempt to start delivering physics data for the first time in 27 months. After an almost two year shutdown and several months of re-commissioning, the LHC experiments are ready to take data at the unprecedented energy of 13 TeV, almost double the collision energy of its first run. This will mark the start of season 2 at the LHC, opening the way to new discoveries.
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.
The Globe of Science and Innovation and its permanent exhibition Universe of particles will be closed to the public until the end of March 2016 for large-scale maintenance work. The renovation project will replace a number of ageing components.
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.
