CERN Ready To Test Fire Its Time Machine On September 10

By - Source: Tom's Hardware US | B 27 comments

Geneva (Switzerland) - Scientists are gearing up to launch the Large Hadron Collider (LHC) a 17-mile long particle accelerator that debuts with the promise to enable science to look deep into the origins of the universe, providing new insights in matter, space and time. The LHC may very well be the most fascinating science project of our generation.

Particle generators usually boast many superlatives and breathtaking specifications that are difficult to comprehend. One year ago, we published an extensive article on Fermilab’s Tevatron, the world’s most powerful particle accelerator, its vision and its astounding accomplishments. On September 10, CERN’s LHC will replace the Tevatron, located in Batavia, Illinois, as the world’s most powerful particle accelerator and collider, at least until a possible 18 mile long linear collider (ILC or International Linear Collider) may be built in the U.S.

While the particle beams created in the Tevatron top out a maximum energy of just under 1 TeV (1 billion electron volts), the LHC can create beams with up to 7 TeV, translating into a maximum collision energy of 14 TeV when two beams cross. LHC scientists said that their particle beams will travel in bunches of 3000, carrying a total of about 100 billion particles. At 99.9% of the speed of light, the beam will travel the 27 km (17 mile) ring structure consisting of a pipe that runs through 1746 magnets (1232 dipoles, 514 quadrupoles, located 150 - 450 ft below the surface)) 11,745 times per second. The energy level of the beam at 7 TeV is about comparable to an average car that is traveling at 1000 mph. A beam may be active for up to 10 hours, which means that its total distance traveled will be about 6.2 billion miles, which is about twice the distance between Earth and Neptune.

The purpose of the LHC, of course, is to create beam collisions. When colliding, scientists expect about 20 collisions when the 200 billion beam particles cross. However, due to the high speed of the beam and the fact that the LHC will cross the beams 30 times per second, there will be 600 million collisions per second at a rate of 600 MHz on average. The difficult task is not only to manage this extremely high and potentially very destructive energy level, but to also read the results of the particle collisions. However, it is nearly impossible for scientists to capture data of 600 million collisions per second with today’s computing technology.

For the first launch and the remainder of the year, CERN scientists will limit the LHC energy level to 5 TeV. LHC will see its first circulating beam on September 10 at the injection energy of 450 GeV (0.45 TeV). Once stable circulating beams have been established, they will be brought into collision, and the final step will be to commission the LHC’s acceleration system to boost the energy to 5 TeV, taking particle physics research to a new frontier. CERN said that the LHC has been prepared for the test for some time: By the end of July, this work was approaching completion, with all eight sectors at their operating temperature of 1.9 degrees above absolute zero (-271° C, 1.9 K).

The next phase in the process is a synchronization of the LHC with the Super Proton Synchrotron (SPS) accelerator, which forms the last link in the LHC’s injector chain. Timing between the two machines has to be accurate to within a fraction of a nanosecond. A first synchronization test is scheduled for the weekend of 9 August, for the clockwise-circulating LHC beam, with the second to follow over the coming weeks. Tests will continue into September to ensure that the entire machine is ready to accelerate and collide beams at an energy of 5 TeV per beam, the target energy for 2008. Force majeure notwithstanding, the LHC will see its first circulating beam on 10 September at the injection energy of 450 GeV (0.45 TeV).

Once stable circulating beams have been established, they will be brought into collision, and the final step will be to commission the LHC’s acceleration system to boost the energy to 5 TeV, taking particle physics research to a new frontier.

The first launch of the LHC will be webcast on http://webcast.cern.ch

    I remember when this first made the news over a year and some ago. They actually calculated the chance of this ending the world. It was something crazy to the -18th power :)

    same question what the hell does it do??
    it would be nice if anyone can convert the above article into a language that normal people can understand

    i would really like to know what it does and i think their would be many other people who have no clue on what the above article means..

    To attempt to recreate the Big Bang and hopefully try and understand how the universe began.

    Yep. The huge amounts of force colliding simulate the beginning stages of the universe on a miniature scale. Scientists are hoping to see what exactly happened in the early stages of the Big Bang, as the end result is pretty apparent.

    Abstract from Dr. Rosslers plea to the world, copy available on LHCFacts.org.

    A nightmarish situation, that can still be hoped to be averted in time through communication within the scientific community, is drawn attention to. Only a few weeks remain to find out whether the danger is real or nothing but a mirage. After this time window is closed, it will take years until we know whether or not we are doomed. The story line has all the features of a best-selling novel. The reader is asked to contribute constructively.

    Quote from Dr. Otto E. Rossler, Professor Theoretical Biochemist, visiting Professor of Theoretical Physics, inventor of the Rossler Attractor, founder of Endophysics, winner of the 2003 Chaos Award of the University of Liege and the 2003 Rene Descartes Award.

    The purpose of the high energy collisions is to try to detect particles that are predicted by modern quantum field theories, but have not yet been detected empirically. Detection or non-detection of any of these particles would be a great step forward for particle physics.

    Perhaps the LHC Rap ( http://www.youtube.com/watch?v=f6aU-wFSqt0 ) can help.

    Ahh Yes. The `Big Bang'.
    That obvious natural phenomenon that just like all natural explosions and bangs since - happened to create perfectly spherical balls of rock floating about in space...
    Odd that that was, thank goodness that dinosaurs and stuff died so that they could get buried in specific locations and magicaly become `fossil fuel' for years to come..

    "Once stable circulating beams have been established, they will be brought into collision, and the final step will be to commission the LHC?s acceleration system to boost the energy to 5 TeV, taking particle physics research to a new frontier."

    errr.... wrong paste? why was this posted twice?

    Am I the only one here remembering you are not supposed to cross the beams?

    ntkeith, you have absolutely seen GhostBusters too many times. We are speaking of theoretical physics, not factual nuclear powered ghost hunter equipment.

    I thought the Big Bang theory was considered ridiculous because it required imaginary invisible undetectable things like dark matter and dark energy to fill in the gaps in mass.

    Scientists enjoy smashing things, just like all of us. The only difference is they prefer to do it on a small scale and at supercalafreakingawesome speeds. They spare no expense for the best quality smahing equipment.

    End of Quote
    I think you have it a little backwards: Big Bang theory was considered ridiculous way back before cosmic microwave background radiation was discovered by Penzias and Wilson in 1965, the actual flash of light, still heard on microwave frequency, the remnant of the BB and right now it is the only scientific theory "still standing". Dark matter is required to explain why Galaxies stay together, instead of flying apart, apparently gravity holding them together is much stronger than we can account for from visible mass and dark energy is trying to explain why expansion of the universe seem to be still accelerating, instead of slowing down. That's where the CERN's LHC comes in, to either prove the BB theory with discovery of new, already predicted particles, or totally new set of questions requiring new theories.
    I think the same people were predicting doom and the end of the world when accelerator at Fermie lab was being build many years ago and we already know how right those predictions were.

    Dumbed downAhh Yes.

    ever hear of gravity ???
    and as for fossil fuel, you probably actually thought that the basis of the theory of how it came about is a load of dinosaurs dying in the one place right? "It is generally accepted that they formed from the fossilized remains of dead plants and animals[1] by exposure to heat and pressure in the Earth's crust over hundreds of millions of years.[2] This is known as the biogenic theory and was first introduced by Georg Agricola in 1556 and later by Mikhail Lomonosov in 1757. There is an opposing more modern theory that the more volatile hydrocarbons, especially natural gas, are formed by abiogenic processes, that is no living material was involved in their formation."As for this organic material all dying in one place, have you ever heard of a forest?? A lot less simple than a shitload of t-rex's dying in the one spot and turning into oil eh? how about you actually look at the science behind these things before you go and have the arrogance to challenge thousands of scientists without even the knowledge that planet formation is the result of gravity, wait you know what gravity is dont you? you know the thing that holds you down? hmmm based on your retarded comment probably not

    Claimintru that information you saw was created by a pr guy he is not even a scientist, there has been a large number of physicist against this even legal action is being taken to stop this project.



    what could happen 1 of 3 things

    1) nothing happens and they get results

    2) they create mini- black holes at velocities slow than speed of light they settle in core of the earth and grow, 5-30 years earth destroyed.

    3) they create a stranglet particle it then causes a chain reaction with all surrounding matter and the earth explodes.

    Thats a 50% chance according to a real group of physicist.

    Its like give a vial of nitro to a monkey , the monkey has no idea what it is and has a 50% chance of blowing himself up.

    I'm no physicist, but isn't TeV a teraelectron Volt, or a trillion electron volts?
