Print Edition - Physics Today

cover: In this December 2006 photograph, the partially assembled 14-kiloton Compact Muon Solenoid particle detector awaits its 100-m descent to a beam-crossing point of CERN's Large Hadron Collider. Visible through the cylindrical detector's 4-m-diameter axial aperture, soon to be packed with tracking chambers, are the concentric rings of the still-unattached far endcap. The small hole at the center will accommodate the vacuum pipe in which the countercirculating proton beams collide in the middle of the detector. The article on page 38 traces four decades of experiments at hadron colliders with ever-increasing beam energies. (Photo courtesy of the UK Science and Technology Facilities Council.)
