LHC repair plan points to weaknesses in original design

Science : Officials at CERN, the European particle physics lab near Geneva, Switzerland, issued a four-page report last week tersely describing how they plan to get the 27-kilometer-long Large Hadron Collider (LHC), the world’s biggest particle smasher, working again after its 19 September breakdown. Although the report doesn’t mention errors in design, the list of fixes does point to flaws, including one that some physicists say cannot be completely eliminated. “There are some questions about the design, and they are fixing some of them and some of them cannot be fixed,” says Peter Limon, an accelerator physicist at Fermi National Accelerator Laboratory in Batavia, Illinois.
