World News : CERN-LHC: First Beam Steared
on 2008/9/10 12:29:50

Geneva, 10 September 2008. The first beam in the Large Hadron Collider at CERN1 was successfully steered around the full 27 kilometres of the world’s most powerful particle accelerator at 10h28 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.”

CERN reiterates safety of LHC on eve of first beam

Geneva, 5 September 2008. A report published today in the peer reviewed Journal of Physics G: Nuclear and Particle Physics1 provides comprehensive evidence that safety fears about the Large Hadron Collider (LHC) are unfounded. The LHC is CERN’s2 new flagship research facility. As the world’s highest energy particle accelerator, it is poised to provide new insights into the mysteries of our universe.

“The LHC will enable us to study in detail what nature is doing all around us,” said CERN Director General Robert Aymar. “The LHC is safe, and any suggestion that it might present a risk is pure fiction.”

Safety has been an integral part of the LHC project since its inception in 1994, and the project has been subject to numerous audits covering all aspects of safety and environmental impact. A comprehensive report by independent scientists addressing safety issues related to the production of new particles at the LHC was presented to CERN’s governing body, the CERN Council, in 2003. It concluded that the LHC is safe. This report was updated and its conclusions strengthened in a new report incorporating recent experimental and observational data that was presented to Council at its most recent meeting in June 2008. This new report confirms and strengthens the conclusion of the 2003 report that there is no basis for any concern about the safety of the LHC.The CERN Council is composed of representatives of the governments of the 20 European Member States of CERN.

The report was prepared by a group of scientists at CERN, the University of California, Santa Barbara, and the Institute for Nuclear Research of the Russian Academy of Sciences. The papers comprising the report have been accepted for publication in leading peer-reviewed scientific journals. The report was reviewed carefully by the Scientific Policy Committee (SPC), a body composed of 20 independent external scientists that advises the CERN Council on scientific matters. Five of these independent scientists, including one Nobel Laureate, examined in detail the 2008 report and endorsed the authors’ approach of basing their arguments on irrefutable observational evidence to conclude that new particles produced at the LHC will pose no danger. The full SPC agreed unanimously with their findings.

“The LHC safety review has shown that the LHC is perfectly safe,” said Jos Engelen, CERN’s Chief Scientific Officer, “it points out that Nature has already conducted the equivalent of about a hundred thousand LHC experimental programmes on Earth – and the planet still exists.”
