The CERN particle accelerator works again – Digital Journal Our Country

Geneva, April 5 (dpa) – The largest particle accelerator in the world, the Large Hadron Collider (LHC), again put in operation today after a phase of modernization of two years, said the European Organization for Nuclear Research (CERN).

For the first time two years ago at the LHC beams circulate again elementary particles, CERN said from Geneva, Switzerland.

Three years after that at CERN were shown the existence of “Higgs boson”, now physicists want to look into other mysteries of the universe. In the coming years expect to find first concrete evidence of the existence of the so-called dark matter, as well as information about their elemental composition.

At 08:41 am GMT began circulating beam protons by 27 kilometers of the LHC, followed at 10:27 by a second beam that rotates in the opposite direction, said CERN. Both beams are now moving with an energy of 450 gigaelectronvoltios (GeV). In the coming days the operators check all systems before that energy is increased.

“We are very happy here, worked great,” he told dpa CERN Director General Rolf-Dieter Heuer, from the center. control Meyrin, near Geneva. “We are excited about how fast you successfully passed the first beam particle accelerator ring,” he said.

But you have to be patient until the particle beams collide inside the underground pipe LHC to high current power, amounting to 13 tera (TeV), almost double than before. “We estimate that (will) about two months,” said Heuer. Until then the machine is calibrated and will intensify and accelerate particle beams.

In the products obtained from the collisions, scientists seek hitherto unknown particles or predicted only theoretically, as was If the “Higgs boson”. According Heuer, is unpredictable when large discoveries into new physics will recur. “It can happen quickly, but can also take a long time, I am cautious about it,” he said.

Scientists at CERN and institutions vinculadan to it hope the findings of Collider serve to confirm or refute complicated theories about the composition and functioning of the Universe. Among them is supersymmetry, which would help close gaps in the standard model and in human knowledge of the bases that support the world.

With the demonstration of the existence of “Higgs” in June 2012, the standard model of existing material was completed so far. But that theory only explains the universe in a very limited way. “We do not understand 95 percent of the universe is dark matter and dark energy,” said Fabiola Gianotti, who in 2016 replaced by Heuer in front of CERN.

Now CERN researchers hope the findings LHC serve to confirm or refute complicated theories about the composition and functioning of the Universe. Among them is the theory of supersymmetry, which would help close gaps in the standard model and in human understanding of the fundamentals of the world.

“We’ll see who discovered the LHC and then discuss what it means for future theories of the structure of the world, “said the Italian Gianotti.

What is clear is that physics is in the first step of a new era with exciting experiments. Is scheduled to run until 2035. renovated LHC And if hitherto the researchers did not discover anything, there are plans for some time for a new and more powerful particle accelerator.
