Last from 53 magnets, necessary for renewal crash-damaged in September, 2008 Large adronnogo kollaydera, on Thursday was tomentous under earth, in the main tunnel of accelerating, press-sluzhba of European organization of nuclear researches reports
(CERN). "It is an important step in the process of renewal (kollaydera). It approaches us to the that point, where we were to the failure, and allows to us to concentrate efforts on setting of the systems which will allow to avoid the reiteration of similar incidents", – a director marked
accelerating subdivision of CERN Steve Mayers (Steve Myers) .bol’shoy adronnyy kollayder – most powerful in history accelerating of elementary particles, created Cernom with participation of physicists from 80 countries, including Russia, and located on the border of Switzerland and France. In
him 27-kilometrovom ring the bunches of protons, dispersed to almost light speed, will clash, RIA Novosti reports.For withholding of bunches of protons so powerful magnets are needed, that for providing with their electricity it is necessary to use superconductors.
In a few days after the start of kollaydera in September one of magnets in a sector 3-4 went out from the sverkhprovodyaschego state and heated to the temperature 100 degrees higher than absolute pitch. Approximately the considerable troop landing of liquid helium was fixed at this time
in a tunnel and kollayder was shut-down.As turned out, as a result of failure many magnets were damaged. In all from a sector 3-4 53 magnets were extracted, 16 from them after examination and cleaning returned into the place, other 37 were transferable on spare. Now, after
more half-year after a failure, quadrupole magnet, intended for focusing of bunch of particles, on Thursday in the day-time was tomentous in a tunnel, and began the trip to "to the workplace" – to the sector 3-4.<
magnets, and on setting of the systems, preventing failures.The new start of kollaydera is set on the end of September, when on a ring the first bunches of protons will begin to circulate. First collisions of meetings bunches, studying which physicists intend to get information about a boson
Khiggsa, expected at the end of October.A chart foresees a short technical stop in christmastides. Then TANK will work out at a stretch to autumn 2010 years, due to what physicists will be able to collect given enough and to report about the first results
in 2010. A plan provides for also, that experiments with the collisions of ions of lead on setting ALICE will begin in 2010.Scientists hope that the results of researches will allow to confirm existence of so urgent boson of Khiggsa – particle, answering after
mass of all other elementary particles. The start of kollaydera was accompanied by ears about that, as though his work will result in education "black holes" and completed by the catastrophe of how hardly not planetary scale, the however scientific resolutely refuted these fears as
not having under itself serious warrants.
