The high-energy physicists will have to chew their brake a little longer. The
LHC, the largest particle accelerator in the world, should probably do collide
beams of protons at the beginning of summer 2009.
It is now official. It was not until late May and perhaps even early June until
10 TeV collisions between two beams of protons take place in the giants
detectors Large
Hadron Collider (LHC). The search for Higgs boson
and supersymmetric particle accelerator with that of 27 kilometers in
circumference and buried about a hundred meters near Geneva will have to wait
... That should boost the morale of American teams hunting parties to the Higgs
with the Tevatron, which have received a intriguing discovery through the CDF
detector. It may be that the discovery of this particle mythical supposed to
explain how and why particles of the universe, like electrons, neutrinos and Z0
boson, have a mass, is finally to European teams.
On 10 September 2008, seemed to take place for the better with the first
movement of proton beams in this fantastic machine-cooled liquid helium below
the temperature of the CMB. The first collisions were provided in the following
weeks when a faulty electrical connection was abruptly interrupted preparations
damaging cooled superconducting magnets to less than 2 K. The repair requires warming and the gradual cooling of a number of magnets, two additional
months of delay were originally planned. The LHC should stop anyway during the
winter to not start again until April but the situation seems more serious than
expected.
It will probably a little more after the December 12, at the Council meeting at CERN. We
should not believe that the situation is critical, however. Problems of this
kind was planned and physicists have seen other when this project started during
the 1980s. In the meantime, be sure to ask questions at the LHC chat with
Etienne Klein on Wednesday November 19 to 18 hours.
