LARGE HADRON COLLIDER

INTRODUCTION TO LHC
LHC the Largest Machine Man Ever made¦
Location: Geneva (It spans the border between France and Switzerland) situated 100 meters underground.
CERN Ëœs Dream Project
CERN Stands for Conseil Européen pour la Recherche Nucléaire
Cost: About 3 BILLION EUROâ„¢s
ie. 3000000000(300crore )EUROâ„¢s
The largest machine in the world.
The fastest racetrack on the planet.
The emptiest space in the Solar System.
The hottest spots in the galaxy, but even colder than outer space.
The biggest and most sophisticated detectors ever built.
The most powerful supercomputer system in the world.

HiStOrY of LHC
The idea of LHC began in early 1980â„¢s .
CERNâ„¢s LEP (Large Electron Positron Collider) ran from 1989-2000.
In 1984, a symposium organized in Lausanne, Switzerland, became the official starting point for work on the LHC.
Civil engineering work to excavate underground caverns to house the huge detectors for the experiments started in 1998.
February 2002:-The last piece of LEP goes up to the surface. In 14 months of dismantling, 40 000 tonnes of material were removed from the 27-kilometre tunnel.
The LHC which was proposed in 1994, replaced LEP and with its facility for experiments to discover the truth about the universe completed its construction in August 2008 .

LHC-LARGE HADRON COLLIDER
LARGE due to its Size (27 km in circumference).
HADRON because it accelerates PROTONS or IONS.
COLLIDER-because the particles are collided at four places where the machine intersect

TARGET OF LHC
PROOF FOR BIG BANG THEORY OF EVOLUTION
HIGGS BOSON
THEORY OF SUPER-SYMMETRY
DARK MATTER, DARK ENERGY
ANTI-MATTER

POWER CONSUMPTION
It is around 120 MW (230 MW for all CERN)
Assuming an average of 270 working days for the accelerator (the machine will not work in the winter period), the estimated yearly energy consumption of the LHC in 2009 is about 800 000 MWh.
The total yearly cost for running the LHC is therefore, about 19 million Euros.
