  13. Large Hadron Collider (LHC) CERN, Genève, CH. • Large Hardron Collider LHC : 27 km • will collide lead nuclei : • Pb + Pb at 2750 AGev+ 2750 AGeV • Maximum available energy for particle production in each collision: • 1,114,000 GeV • (= 0,1 mJoule. Each nuclear collision equivalent to 1 mg hitting a wall at 50 km/hr) • But the energy is concentrated in a volume of less than 10 -45 m3 ! • Highest ENERGY DENSITY • ever produced.
