LHC restarts after two year of renovation
World’s largest and most powerful particle collider, Large Hadron Collider has restarted with protons now circling the machine's 27km tunnel for the first time since 2013.

The collider, which was temporarily shut down is now allowing particle beams to travel in both directions inside parallel pipes at a speed just a notch below that of light. But actual collisions will not begin for at least another month. With the improved collider, the world can now expect it to collide particles at nearly double the energy the LHC reached during its first run.

Built by the European Organization for Nuclear Research (CERN) from 1998 to 2008, the collider is now looking to go beyond the Standard Model. The beams have launched a week or so later than originally scheduled, due to a now-resolved electrical fault. Over the coming months, engineers will gradually increase the beams' energy to 13 trillion electron volts: double what it was during the first operating run.

Currently, the engineers have spotted splashes of particles, which occur when stray protons hit one of the shutters used to keep the beam on-track. If this happens in part of the pipe near one of the experiments, the detectors can pick up some of the debris. With the new round of exploration, LHC aims to find sibling particles for its initial detected Higgs particle. The scientists at CERN had used the machine to discover the Higgs boson, commonly called as the God’s particle, in 2012.

The organization at the helm of LHC is supervised by 21 member states and the experiments are conducted by citizens from many other countries. About 3,000 students are involved in the present operations. While CERN is based near Geneva, Switzerland, the ring itself extends underneath the border with France.
