摘要

The LHC Collider start-up was successfully achieved on the 10September 2008. This date is a milestone marking a long path started fourteenyears ago with the LHC approval in December 1994. But other milestones are nowexpected. In fact, after about 10 days of operation, the LHC was subjected toa major stop caused by a faulty interconnection on the magnets interconnections.The fault caused severe collateral damages. This paper shortly recalls some of theachievements of the 10 September start-up and focalizes on: the incident of the 19thof September; its causes and the collateral damages; status of reparation; overlookon the modification made on the Accelerator to limit the repetition of such type ofaccident and finally looking toward the 2009 Commissioning.
