GENEVA 12 March.- The Large Hadron Collider (LHC) began operations again progressively and will reach its maximum power May , with the confidence of the community of physical to open new windows of knowledge and will result in discovery expand the frontiers science .
“This may be a new era for science,” said Dave Charton, spokesman ATLAS detector, one of four experiments that take place on the accelerator of the European Center for Particle Physics (CERN).
There are a number of questions that try to respond, “he said at a press conference to present the new stage of operation of the accelerator, which is three years, before entering a new period of technical review.
LHC is the most powerful machine that exists, with conductive magnets which work like batteries, and its stored energy equivalent to that of an aircraft carrier traveling at 43 miles per hour or an Airbus 380 flying at 700 miles per hour.
The accelerator has the shape of a ring 27 kilometers in circumference and is located within about 80 meters underground, on the border of Switzerland and France tunnel.
To function required to be a rather low temperature of 217 degrees Celsius that space, which was achieved late last year.
We’ve worked hard to improve the detector and have demonstrated (during the first stage of operation) we are able to exceed expectations. We hope we can surprise again, “said Tiziano Camporesi, spokesperson of the CMS experiment, one of which houses the accelerator.
The scientist was referring to the greatest discovery in the ATLAS and CMS experiments in 2012: the Higgs boson, which came to confirm the Standard Model in particle physics that
is based Thus, it was found, first, their existence experimentally and no. only in theory.
In the past two years, the accelerator has been reviewed minutely, with each piece and connection that has gone through controls to prepare to support the energy reach of 13 TeV ( teraelectronvoltios), almost double the power of the first stage.
That energy level will be reached in May, following a gradual increase in a process that has already begun, said CERN Director General Rolf Heuer .
When you arrive at 13 TeV proton collisions will occur at a comparable power that is needed to melt one ton of steel, told Efe Chief Technology CERN, José Miguel Jiménez .
To do this, the particles began to be introduced this weekend on the accelerator and is expected to begin to move-in opposite directions which then produce the colisiones- within the ring in about two weeks.
Since then, physicists at CERN calibrated direction of the protons, which can not be achieved only with the automatic procedures for measuring and correcting available to the LHC, explained the responsible infrastructure of the organization, Lluis Miralles.
This calibration is vital to the extent that, once the optimized procedure, proton beams will 11 000 revolutions per second at 27 kilometers off the accelerator.
The level of accuracy for the protons collide-and thus produce the data needed by physicists is comparable to having two arrows diameter of a needle, shot 47 kilometers (facing each other ) and whose tips are halfway.
All to discover “another model of physics that goes beyond what we know and can not explain what we see,” said Miralles.
