LHC; successful attempts COLLISIONS subatomic particles to enter new era
GENEVA .- With a year and a half late to adjust and calibrate the LHC and with 6 failures after scientists in charge of the largest particle collider in the world indicated that managed to trigger accelerated proton collisions at 0, 9999999% the speed of light (up to 1000 million km / h) and generate a record energy 7 trillion electron volts to try to recreate Condic ions similar to the Big Bang after 2 fractions of seconds for which the universe emerged. This first joy
generated a party to celebrate the first step of a new era of scientific studies on the matter in the near future will answer some questions about the creation of the universe.
"This is pure physics in action, the beginning of a new era, with collisions of 7 TeV [tera]," said Paola Catapano , scientific spokesman for the European Centre for Nuclear Research (CERN) in Geneva, to take part the experiment illustrated Steve Myers and technological prowess to align infinitesimal particle beams by superconducting magnets cooled close to absolute zero temperature. "It's a great time for science", said CERN Director General, Rolf Heuer, in a videoconference from Japan, barely containing his excitement.
The cheers of joy broke into the ATLAS control room when the detectors Large Hadron Collider (LHC), 27 kilometers long and 100 m deep, installed at the border between France and Switzerland, marked the collision of particles s ubatómicas to nearly the speed of light. Twice circulating beams in opposite directions by the Large Hadron Collider (LHC , English acronym), the CERN accelerator, failed to achieve their goal and you were lost Karsten Eggert said he had begun at 5 am (time 0 in Argentina .)
"We are a billionth of a second after the Big Bang", AFP said CERN spokesman James Gillies.
"Certainly we will be repeating the feat several times in the next week and during the year," said the scientist , who had compared the experiment with the launch of two needles from different sides of the Atlantic, waiting to collide.
"We had some small problems, "said Paul Collier, head of CERN's beam. " It's the kind of thing that happens with such a complex machine. In an hour and a half inject a new beam. Meanwhile Mario Martinez, a English scientist of the ATLAS experiment - one of the four large detectors responsible for collecting the information generated from the collision- explained that whenever a failure should attempt to restart a process that takes about three hours where you have to relax the magnets, re-inject protons and start increasing the power.
"After almost 20 years, now let exploring new territory," said the Swedish scientist Erik Johansson, explaining that accelerating and colliding protons secret hope to solve that energy and dark matter, which forms most of the universe, antimatter or find the famous Higgs boson particle ( called the God particle ), a kind of cosmic molasses scattered in space that would be the mass of subatomic particles interact. The existence of this particle, is considered essential to explain why elementary particles have mass and why the masses are so different.
"Now we are just trying to two beams in each direction, but at the end of the experiment within two years, we want to do collision about 2800 in each direction, to cause millions of collisions, after which there will be a stop for a year, "said the scientist Michael Barnett. Seven TeV is half the rated power throttle, and only after that long pause, where it has been thoroughly reviewed all the gear, we will try to reach speeds of 14 TeV.
What gave birth to the cosmos was the violent expansion of matter and energy in space-time a temperature that reached a billion degrees in there was a "soup" of particles interacting with each other in various mergers atomic and what is intended emulate the conditions of that moment after the first major expansion, which reproduces the Big Bang is impossible said Dr. Maria Teresa Dova, a researcher who works at CERN of the Universidad Nacional de La Plata (UNLP). This milestone
science and technology is the first step of the beginning of a great adventure without limit will advance knowledge of the matter does not emit dark subcategories radicción but constitute 23% of the density of the cosmos and that together with the hypothetical dark matter would be responsible for the universe to expand rapidly. Also the LHC could clarify the existence of supersymmetry to postulate that each particle has a partner who is attracted and hence the asymmetry between matter and antimatter without which we and the universe exist.
The new stage, called "Physics First" is the beginning of a series of similar clashes million over a period of 18 to 24 months.
should be analyzed in many millions of collisions to detect results that are interesting to define the scientific pose our questions and scientists pose perform 200 events / sec in order to select the algorithms necessary to enable us to learn by doing, to discover the particles of interest to us as the graviton or others that make up dark matter. In this regard the experiment could also clarify the "dark matter" and "dark energy" invisible matter could explain 96% of cosmos.Aun so, the LHC is currently operating without its full potential because it's designed to produce collisions at a rate of 14 TeV, or 99.99% the speed of light, which could reach 2012.
also need to deepen knowledge on the GRID, the high-speed electronic network that allows scientists to participate in real time in the experiments.
In the coming months will slowly climb forward in numbers by preserving shock and thus avoid instabilities us little by little iremos conociendo como y cuáles son los ojetivos científicos buscados.
