Spectators look at the ATLAS detector construction (a Toroidal LHC Apparatus) at the CERN (Centre Europeen de Recherche Nucleaire) near Geneva, Switzerland, Thursday, May 31, 2007. The detector will be placed around the large hadron collider (LHC), CERN's highest energy particle accelerator. ATLAS is a general-purpose detector designed to measure the broadest possible range of particles and physical processes that could result from the collision of the proton beams within the LHC. A pilot run of the LHC is scheduled for summer 2007. (AP Photo/KEYSTONE/Martial Trezzini)
