    : : skip to main skip to sidebar The Science of Conundrums THE IMPACT OF MEGASCIENCE Thursday , September 25, 2008 LHC Quench Stops CERN : Re-start Delayed Again After last Friday's massive quench at the LHC , CERN has announced that re-starting the collider will have to wait even beyond 2 months for repairs and downtime . With a planned winter shutdown in late November , even if the collider were ready , there would not be enough time to continue tests . Re-start of the LHC should be in April 2009. Day 7 into the major accident damaging part of the LHC helium cooling and superconducting magnet systems , indicates little progress as yet . Scientists at CERN are still investigating the failure in Sector 3-4, an eighth of the 17 mile ring of magnets that are normally cooled to near absolute

  • Accident Cripples LHC

    : skip to main skip to sidebar The Science of Conundrums THE IMPACT OF MEGASCIENCE Friday , September 19, 2008 Accident Cripples LHC No collisions , no beams either next week at the LHC . The BBC reports an alarming quench of about 100 superconducting magnets today , that heated up as much as 100 C . A tonne of liquid helium spilled into the tunnel and the CERN fire brigade went in . Cause of the quenching has not been announced , nor have any injuries been reported . Liquid helium leaks vaporize back to a gas almost instantly and would freeze or choke personnel . present Ordinarily magnet quenches occur when proton beams are lost or scatter into magnets , causing helium coolant and magnets to heat and lose their superconductivity and their power to keep proton beams within the collider .

A thunderstorm last Friday knocked out some transformers at the LHC near Geneva that are part of the helium cooling system , that cools the magnets that keep the proton beams travelling near light speed on a circular path through the collider . Technicians have been scrambling to fix the problems , but not before some magnets warmed well above standard operating temperatures , some reaching almost 7K from the usual ultra cold 1.9K Electromagnets at the LHC need to be this cold to be superconducting , or at peak efficiency , in order to deliver extremely high magnetic fields in the 27 km ring of 1200

We are 2600 dont mess with us was their . sign-off One of the CMS team fighting off the hackers said it was a scary experience Dr James Gillies , chief spokesperson for CERN said It was quickly detected . A half dozen files were uploaded by the hackers . One CMS computer file was damaged . It could have been worse . An CERN insider commented that if the attackers had penetrated into a second computer system , some of the CMS could have
