    Last night the LHC re-established circulating beams.

    CERN has issued a http://press.web.cern.ch/press/PressReleases/Releases2009/PR16.09E.html" [Broken].

    :rofl: "If you can check this link, then the answer is probably..."


    Still, statements like this one from CERN in V50's link are probably not real helpful:
    Sounds too much like HAL, or the Forbin Project. A little more careful PR person should probably be hired...


    EDIT -- Never anthropomorphise particle accelerators. They hate it when you do that.

    The first time I read that quote, I thought, "It's not a bad machine - it's just misunderstood!"

    I blame it all on the mini black holes they are generating.

    The LHC is injecting the two proton beams from the SPS at 450 GeV. This lower than the energy reached by the Tevatron (512 GeV) on July 3, 1983, the first day acceleration was attempted. The Tevatron collider is now (and has been for many years) running at about 980 GeV per beam (proton on anti-proton). So until the LHC energy exceeds 980 GeV per beam, there is no need to worry about black hole production.

    There is no need to worry about black hole production period.

    The LHC certainly tried everyone's patience. I'm happy they got it powered up. It felt like a countdown to a new year.

    LHC has 2 countercirculating beams now.

    First collisions (at injection energy) this afternoon.

    And Geneva is still on the map, right? :biggrin:

    Maps actualization is a slow process.
