For the first time, on the night of 20 May 2015, protons collided in the Large Hadron Collider (LHC) at CERN at the record-breaking energy of 13 TeV.
These test collisions were part of the systems set up that includes adjusting the collimators that protect the machine and detectors from particles that stray from the edges of the beam. These devices, which absorb stray particles were fine tuned to ensure that the LHC magnets and detectors are fully protected.

The start of the LHC’s second run is planned for early June.
