Question: You said you visited CERN,How does a Hadron Collider Work?

Connor Macrae answered on 21 Jun 2015:

The simple answer is it uses a series of linear (straight line) and circular particle accelerators to accelerate particles such as protons to as close to the speed of light as possible – about 99.99%! This acceleration is generated by super cooled magnets that each give energetic ‘kicks’ to the particles whilst bending their trajectory to keep them shooting in the direction we want. In the end, two particle beams that are going around the largest ring are directed to collide inside one of the LHC’s detectors, like the ATLAS detector. All the different trajectories of the particles produced are mapped by these detectors for scientists to analyse for new particles.
