The Large Hadron Collider or LHC restarted this week. The hadron collider is the world’s most powerful atom smasher which provides a glimpse of the world as it existed just milliseconds the big bang. The machine is one gain available for experimentation after 2 years of repair works. The improved hadron collider is now stronger than before.


The machine once again started 10.41 am local time at Geneva, Switzerland on 5th April when a proton beam was passed along the 17 mile long ring-shaped hadron collider. At 12.27 pm, another proton beam passed the ring from the opposite direction.

Large Hadron Collider restarted

The officials of the European organization for nuclear research CERN reported the commencement of operations.

The energy levels hit by LHC were 450 GeV. One GeV is equivalent to the mass of one proton. According to reports, the LHC operators want to achieve the highest energy of proton beam levels in LHC.

According to Fredrick Bordry, CERN director, the LHC is now much improved but still its performance is to be analyzed when it comes to increasing the energy levels of the proton beam to new record levels.

According to reports the CERN statement describes the upgrade and repair of LHC as a herculean task. The upgrade included consolidation of around 10,000 electrical connections between the magnets located inside the LHC, adding of more protection for the magnets and improving other aspects of the collider. The upgraded LHC bunches protons more closely in beams so that more collisions can take place.

The old LHC discovered Higgs boson when it operated at 8TeV.  If the scientists manage to achieve higher energy levels of 13TeV then there are chances of discovering more exotic atom particles.

According to James Siengrist, the associate director of science for energy physics at the U.S. department of Energy, the discovery of Higgs boson is one of the greatest achievements of modern times. He says that the restarting of LHC presents wide possibilities and USA will be in the fore front of these discoveries.

10,000 experts from 113 countries, including 90 from U.S. universities and 7 from U.S. DOE national labs have helped to design, build and now upgrade the LHG.
