First beam in the LHC -- accelerating science

Geneva -- The first beam in the Large Hadron Collider at CERN[1] was
successfully steered around the full 27 kilometres of the world's most
powerful particle accelerator at 10h28 [0826 UTC] this morning. This
historic event marks a key moment in the transition from over two decades of
preparation to a new era of scientific discovery.

"It's a fantastic moment," said LHC project leader Lyn Evans, "we can now
look forward to a new era of understanding about the origins and evolution
of the universe."

Starting up a major new particle accelerator takes much more than flipping a
switch. Thousands of individual elements have to work in harmony, timings
have to be synchronized to under a billionth of a second, and beams finer
than a human hair have to be brought into head-on collision. Today's success
puts a tick next to the first of those steps, and over the next few weeks,
as the LHC's operators gain experience and confidence with the new machine,
the machine's acceleration systems will be brought into play, and the beams
will be brought into collision to allow the research programme to begin.

Once colliding beams have been established, there will be a period of
measurement and calibration for the LHC's four major experiments, and new
results could start to appear in around a year. Experiments at the LHC will
allow physicists to complete a journey that started with Newton's
description of gravity. Gravity acts on mass, but so far science is unable
to explain the mechanism that generates mass. Experiments at the LHC will
provide the answer. LHC experiments will also try to probe the mysterious
dark matter of the universe -- visible matter seems to account for just 5%
of what must exist, while about a quarter is believed to be dark matter.
They will investigate the reason for nature's preference for matter over
antimatter, and they will probe matter as it existed at the very beginning
of time.

"The LHC is a discovery machine," said CERN Director General Robert Aymar,
"its research programme has the potential to change our view of the Universe
profoundly, continuing a tradition of human curiosity that's as old as
mankind itself."

Tributes have been coming in from laboratories around the world that have
contributed to today's success.

"The completion of the LHC marks the start of a revolution in particle
physics," said Pier Oddone, Director of the US Fermilab. "We commend CERN
and its member countries for creating the foundation for many nations to
come together in this magnificent enterprise. We appreciate the support that
DOE and NSF have provided throughout the LHC's construction. We in the US
are proud to have contributed to the accelerator and detectors at the LHC,
together with thousands of colleagues around the world with whom we share
this quest."

"I congratulate you on the start-up of the Large Hadron Collider," said
Atsuto Suzuki, Director of Japan's KEK laboratory, "This is a historical
moment."

"It has been a fascinating and rewarding experience for us," said Vinod C.
Sahni, Director of India's Raja Ramanna Centre for Advanced Technology, "I
extend our best wishes to CERN for a productive run with the LHC machine in
the years to come."

"As some might say: 'One short trip for a proton, but one giant leap for
mankind!' TRIUMF, and indeed all of Canada, is delighted to bear witness to
this amazing feat," said Nigel S. Lockyer, Director of Canada's TRIUMF
laboratory. "Everyone has been involved but CERN is to be especially
congratulated for bringing the world together to embark on such an
incredible adventure."

In a visit to CERN shortly before the LHC's start-up United Nations
Secretary General, Ban Ki-moon said: "I am very honored to visit CERN, an
invaluable scientific institution and a shining example what international
community can achieve through joint efforts and contribution. I convey my
deepest admiration to all the scientists and wish them all the success for
their research for peaceful development of scientific progress."
