The scientists across the globe looked on with bated breath as the Large Hadron Collider (LHC) was restarted on Sunday at CERN, a particle physics laboratory near Geneva, after being kept in the shutdown mode for an important upgrade for almost two years since February 14, 2013.
“Congratulations…Now the hard work starts,” Rolf-Dieter Heuer, CERN director general told thousands of employees from the control room upon successful restart of the LHC.

Today’s the day! Beams to circulate in the LHC for 1st time in 2 years. Follow the action here http://t.co/gpstfXp2mT #RestartLHC

According to the scientists, the LHC will take roughly a month when the results of the first collisions will start appearing.
Once the LHC starts working in full swing, the priority of physicists will be to discover the dark matter during current run.
The dark matter is the invisible material that constitutes over 25 percent of the universe.
The discovery of the hidden extra dimensions will be equally important as it will explain the reason behind the weakness of gravity as compared to other forces of nature. Moreover, it will offer an explanation for why the world is not composed of anti-matter.
The scientists behind the project will be well equipped with the latest modifications of the Large Hadron Collider. The LHC has been equipped with safer magnets having Quench protection. This will help in dissipating energy in a more controlled manner. The most exciting transformation for the scientists will be the higher energy of the proton beam. According to the scientists, LHC can now circulate the beams of 13 Trillion electron Volts (TeV) which is five notches above the previous 8 TeV.
This will result in high energetic collisions, making the chances of detecting newer particles brighter. To raise the collisions rate, the lag between two proton packets was lowered to 25 nanoseconds from the earlier 50 nanoseconds.
The scientists have also tried to make the Large Hadron Collider machine safer with the use of radiation resistant electronics. Moreover, the scientists used non-evaporating getter inhibiting electron cloud buildup for covering the interiors of the vacuum tube.
