INTRODUCTION

Large Hadron Collider (LHC) is the world largest particle accelerator, it lies in a tunnel below CERN, a European physics lab outside of Geneva.

How it works:
Billions of protons are loaded into the LHC then by using the electric field created by the magnets along their path, they are able to accelerate 2 proton beams at the speed of 6.5 TeV for each beam. After reaching that speed the two beams collide head on.

History:
The LCH first run gave the evidence to test out the standard model, a theory which describes that the universe is made up tiny particles, and give the rules on how these particles behave. The first run also helps discover the Higgs Boson.

Present:
The world's newest particle accelerator, Super KEKB, shown, just a baby with its 3km circumference, compared to the 27km circumference of the Large Hadron Collider (LHC). But it is designed to deliver more than 40 times more collisions between particles than its predecessor. Read more at daily mail.
