7. CERN’s Mandate:
building and running particle accelerators
The Large Hadron Collider (LHC) will be the most powerful instrument for the investigation of particle properties ever built.
Four large underground caverns for the detectors.
The accelerator that produces the highest particle energy of movement in the world.
The most intense beams for particle collisions.
The LHC will operate at a temperature below that of the outer space.

8. Around 9000 of the 17000 accelerators operating in the World today are used for medicine.
