8:51 science is increasingly playing near the origin of the universe. In the "God Machine" scientists of various nationalities, including several Argentines managed to play the instant after the Big Bang, the explosion that gave birth to the cosmos.
The largest particle accelerator in the world (LHC by its French acronym) today set a new record for high-energy collisions when you collide two beams of protons to force triple the previous mark.
This large hadron collider colliding beams made as part of its ambitious program to discover new details about theoretical and Micropower particles that gave rise to the universe.
collisions begin a new era for researchers who work in underground facilities under the Swiss-French border.
Scientists in the control room of the European Organization for Nuclear Research (CERN for its French acronym) burst into applause when registering the first collisions. Colleagues around the world connected through the Internet.
" We have seen traces of collision
perfect
, the detector works well "said Fabiola Gianotti Italian physics, head of Atlas, the name is known to one of four teams who participated in the experiment." Begins a new era of particle physics. This is a time of excitement and congratulations to those responsible for the LHC for the excellent work done on this machine only ", he added. collisions of two proton beams from 3.5 TeV (tera) each started very early this morning, but the first attempt to achieve the milestone failed due to a problem
detected between the LHC and the accelerator prior to fire protection system the machine. The operation was resumed by midday in Europe, with the gradual rise of the beam energy to 3.5 TeV expected. At one, had barely managed to perfectly align the finest particle beams circulating at almost the speed of light. All those around Atlas burst into applause when detecting the first collisions. The director general of CERN, Rolf Heuer, congratulated all the laboratory in Geneva via video link from Japan , which was next to the laboratory's scientific director, Sergio Bertolucci. "
's a great time for science , I think that is the principle a long and exciting tour of particle physics, "Heuer said. Although the detectors have continued to crash, about 30 per second at Atlas, said Gianotti-physicists and engineers are optimizing the particle beams, stabilizing them to improve the results. But the scientific world are given by infinitely pleased with the achievement of the first collisions.
However, still must wait months to see if the "God particle"-the would explain why things have mass-exist.
After el primer encendido del acelerador
en septiembre de 2008,
un accidente grave provocado por un cortocircuito y que afectó gravemente a parte de los imanes que lo forman e interrumpió el plan de puesta en marcha . Un año se tardó en reparar los desperfectos. El pasado 20 de noviembre se puso de nuevo en marcha el LHC, con el primer haz de partículas circulando a 0,45 TeV. Diez días después, se aumentó ya la energía hasta 1,18 TeV. Cuando el 16 de diciembre se detuvieron estos primeros ensayos se había logrado hacer colisiones a 2,36 TeV.
En este período inicial los detectores registraron more than a million collisions , interesting to calibrate the equipment, but even without scientific evidence. After a stop for adjustments, the LHC was turned on again on February 28 and March 19 reached 3.5 TeV. CERN experts spent a whole month to try and stabilize the beams before the first crash today.
The future plan is to take data continuously for 18 or 24 months , with a brief stop at the end of this year, in which the first is expected to make scientific discoveries. Then interrupt the operation of the LHC to make technical improvements needed to start a new phase of work ahead with twice the power: beams of 7 TeV to cause collisions to 14 TeV.30, 0310Clarin
