MOSCOW, March 25 – RIA Novosti. Scientists at the European Organization for Nuclear Research (CERN) to postpone the launch of the Large Hadron Collider (LHC), due to a short circuit in the wiring of one of the most important magnets, CERN said in a statement.

“Current evidence suggests that the delay (start) can range from a few days to a few weeks” – quoted statement Reuters.

It was planned that on Wednesday, engineers will begin test runs proton beams at the LHC. This is a preparation for the main part of the experiment on the collision of charged particles towards the end of May.

The LHC has suspended its work in 2013 for scheduled maintenance after three years of intensive work. In the next two years, hundreds of engineers, scientists and technicians updated equipment complex machine, reinforced particle accelerator LHC and prepared to work with the new facilities. The total capacity of particle collisions in the LHC will reach 13 TeV to 6.5 TeV per beam. This is almost two times more than the previous peak reached in 2012, when the power of the collider was 8 TeV – 4 TeV per beam. In this case, the planned capacity of 14 TeV LHC, but it has never been achieved in the course of the collider.

In particular, in the collider have been replaced 18 of the 1232 superconducting magnets bipolar, which hold, adjust the direction and focus particle beam accelerator. The remaining magnets have provided improved protection system cooling, during which they release large amounts of energy. The new system will help to better control the dissipation of the energy, in order to avoid damage to the collider. Improved as the LHC cryogenic system, allows the magnet to work at low temperatures.

The updated Collider will run for three years, until a new technical stop to check the equipment.

One of the purposes of the second run will be to find the LHC dark matter. It is assumed that the discovery of this matter will help solve the problem of dark matter, which, in particular, is abnormally high speed rotation of the outer regions of galaxies.

Large Hadron Collider built by the European Organization for Nuclear Research (CERN) with the participation of physicists from many countries including from Russia. It is located on the border of Switzerland and France. In its 27-kilometer ring will collide beams of protons accelerated to nearly the speed of light.
