	It 's the world's largest machine There is a structure that is the world's largest 27 km ; light despite its size is only 38,000 tons weighs less than 50 Eurostar trains. CMS experiment, 12,500 tons, 7,000 tons ATLAS experiment. IN CMS there is more iron than the Eiffel Tower.
	E 'the coldest place in the universe but also the hottest spot of the galaxy Much of this machine is kept at a temperature over 271 degrees below zero . As the collisions occur at points where it reaches a temperature 1000 billion times greater than Heart of the Sun
	Each of the filaments 6300 superconducting niobium-titanium present in the LHC has a thickness of about 6 thousandths of a millimeter , 10 times thinner than a human hair.
	The protons will travel in the LHC, once they reach the maximum energy at a rate equal to 0.999999991 the speed of light, that is very close to top speed Universe.
	Each proton make every second, 11,000 revolutions ring of 27 km
	beams of protons will cross 40 million times per second.
	number of collisions in the system: up to 25 collisions between protons every 25 nanoseconds (billionths of a second), or about 1 billion collisions per second.
	LHC is composed of 2000 superconducting magnets maintained at a temperature of -271 ° C
	It 's the biggest factory of the world's information Each year, the data produced by the LHC experiments will produce the equivalent of one hundred thousand DVD.

	Pa rtecipazione Italian LHC
	Italy participates in the construction LHC at CERN as part of its contribution as a member (the division of budget between CERN member countries is made according to GDP)
	in 2006, Italy contributed to 12.3% of the budget of CERN amounted to 77.06 million of €
	Italian industry had a return of the sun orders paid with a total budget of about Cern € 88 million (which is above the Italian contribution to CERN)
	this return are added to the domestic procurement orders from INFN.

	Return industrial
	In recent years physics has increased its effects on industry, from CERN. While the contribution of the Italian state was stable over the past 5 years (79 million euro), the industrial return has risen from 33 million € in 2001 to 54 in 2002 to 66 in 2003 to 88 in 2004 and 2005.
