Large Hadron Collider is in an underground tunnel stretching for almost 27 km

In the Large Hadron Collider began experiments to search for “dark matter,” according to the European Organization for Nuclear Research (CERN), who oversees the world’s largest particle accelerator. This happened more than two years after the forced stop of the accelerator.

The experiments were started at about 7 am local time (8 am Moscow time). Follow their progress is possible in the official blog at CERN.

Scientists hope that using the collider in the near future be able to come close to solving the existence of “dark matter” – this is a hypothetical form of matter does not emit electromagnetic radiation, which makes it impossible her direct supervision.

In order to achieve the desired and determine whether or not there is a matter, scientists are going to bring the work of the ILC in hitherto unprecedented power – 13 teraelectronvolt. It’s almost twice as much as the energy of the accelerator first run.

“This will mark the beginning of the second season of operation the LHC, which will open the door for new discoveries,” – said the CERN site.

Test starts in 27-kilometer looped tunnel at a depth of around 100 meters on the border of France and Switzerland, began in April, when the tank was opened after renovation.

“Open the tap “

The experiments were conducted on the accelerator as follows: scientists sent proton beams in parallel to double the collider tunnel so that the protons move in a circle in different directions. In the tunnel, there are several points of intersection where the accelerated particles collide.

Specialty Detectors remove information about the processes occurring in collisions, and send it to the control center, where scientists analyze the data.

Right now, we really obtain access to relevant information about clashes to power 13 teraelectronvolt

“Right now, we really obtain access to relevant information on the clashes on the power 13 teraelectronvolt . It’s a bit like the way you open the tap, “- says Professor Dan Tovey at the University of Sheffield.

” Over the next few months, the frequency and power of collisions will increase significantly, and by the middle of the summer we will have enough Information to start research beyond the Standard Model, which we could not proceed under the previous collider power “- hoped the scientist.

One of the achievements of the first season of operation of underground installations officially launched in autumn 2008, it was estimated the discovery of the Higgs boson – the particle that makes other particles acquire mass.

On the Large Hadron Collider, researchers are working around the world. It was reported that three thousand scientists involved in the project, about 300 – Russian physicists.
