Physicists and engineers in Brookhaven National Laboratory's Superconducting Magnet Division are in the final stages of assembling "replacement" magnets for the Large Hadron Collider (LHC) at Europe's CERN laboratory. Brookhaven built twenty magnets already installed at the 17-mile circular collider—based on designs initially used for the Relativistic Heavy Ion Collider here at Brookhaven. The replacements are intended to be on hand for as quick a switch as possible if they are needed. The Brookhaven team is also working on new magnet designs with improved capabilities for the LHC.
