It is a remarkably harmonious international
collaboration in which the UK has a leading
role. British scientists and engineers have
prominent roles in construction, management
and experimental teams and the UK makes a
significant contribution to the LHC budget.

The LHC is physicallylocated in a circular27km (16.5m) longtunnel under theSwiss/French borderoutside Geneva, but asan international projectthe LHC crossescontinents and manyinternational borders.In the UK, engineersand scientists at 20research sites areinvolved in designingand buildingequipment andanalysing data.

This photo shows a view of
the Large Hadron Collider
in its tunnel at CERN
(European particle physics
laboratory) near Geneva,
Switzerland. Scientists of
the CERN started the Large
Hadron Collider (LHC) on
September 10 for the first
time and successfully.

the LHC is
designed to
accelerate sub-
atomic particles to
nearly the speedof light and then
smash them
together
replicating
conditions which
prevailed in split-
seconds after the
"Big Bang" that
created the
Universe 13.7
billion years ago.

Built in a tunnel 100 metres
(325 feet) below ground in acomplex straddling the
French-Swiss border, the LHC
is designed to accelerate sub-
atomic particles to nearly thespeed of light and then smash
them together replicating
conditions which prevailed in
split-seconds after the "BigBang" that created the
Universe 13.7 billion years
ago.

Scientists fired a first beam of protons around a 27-kilometer (17mile)
tunnel housing the Large Hadron Collider. They hope to recreate
conditions just after the so-called Big Bang. The international group of
scientists plan to smash particles together to create, on a small-scale,
re-enactments of the Big Bang.

The LHC is still new, but its
successor - the InternationalLinear Collider (ILC) is alreadybeing discussed. So why buildtwo high energy colliders thatoperate on the same principles?
The LHC is a discoverymachine, a general purpose toolthat will open up new areas ofphysics and demonstrate theexistence, or not, of predictednew laws and particles. The ILCis a precision instrument thatwill allow scientists to explorein detail the discoveries made
by the LHC.
