First beam in the LHC
First beam in the LHC - accelerating science
A historic moment in the CERN Control Centre "The beam was successfully steered around the accelerator in 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 in morning at Geneva, 10 September 2008. This historic event marks a key moment in the transition from over 20 years of preparation to a new world of scientific discovery.
The Large Hadron Collider (LHC) — built since 2003 at a cost of $3.8 billion — will provide scientists with much greater power than ever before to smash the components of atoms in a bid to see how they are made.
“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.
The LHC, as the collider is known, will take scientists to within a split second of a laboratory recreation of the big bang, which they theorize was the massive explosion that created the universe.
The project organized by the 20 European member nations of CERN has attracted researchers of 80 nationalities. Some 1,200 are from the United States, an observer country which contributed $531 million. Japan, another observer, also is a major contributor.
The collider is designed to push the proton beam close to the speed of light, whizzing 11,000 times a second around the tunnel.
Smaller colliders have been used for decades to study the makeup of the atom. Less than 100 years ago scientists thought protons and neutrons were the smallest components of an atom's nucleus, but in stages since then experiments have shown they were made of still smaller quarks and gluons and that there were other forces and particles.
The CERN experiments could reveal more about "dark matter," antimatter and possibly hidden dimensions of space and time. It could also find evidence of the hypothetical particle — the Higgs boson — believed to give mass to all other particles, and thus to matter that makes up the universe.
Some scientists have been waiting for 20 years to use the LHC. But even their younger colleagues are excited that startup has finally arrived.
"I think it's a very important project," said Katie McAlpine, 23, a Michigan State University graduate who made a rap video about the project.
"It's mostly out of scientific curiosity, what is the universe made of? How does it work? What are the rules? That's very exciting and it's important to advance our knowledge," she told Associated Press Television News.
She said she was surprised by the success of the video, which has had more than a million views on YouTube and which has received approval from CERN for its scientific accuracy, especially in its success with young people.
"I was really hoping that this would get taken into classrooms," McAlpine said. "I don't imagine that elementary school and most middle school children will understand it very well, but a lot of parents have e-mailed me, saying I have a 9-year-old or a 7-year-old and showed them your rap and they really love it.
“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.”
“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.”-United Nations Secretary General, Ban Ki-moon said in a visit to CERN shortly before the LHC’s start-up.
“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.”
“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.”
“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.”
Apple’s jump into the Intel bandwagon has been very beneficial for the company when it comes to sales. However, there are rumors that Apple will no longer include intel chipset in their future MacBooks. According to rumors, Apple might develop its own chipset or perhaps look for a suitable alternatives like NVidia chipsets.
