LHC. The Large Hadron Collider (LHC) is an accelerator with 27 km circumference. Being built on the France- Switzerland border west of Geneva. It will start to run at 2007. High luminosity: 1034 cm-2s-1 High center of mass energy: 14 TeV p – p collisions every 25 ns. CMS EXPERIMENT.
LHC. L=10 27 cm -2 s -1 with b =0.5m and ~600 bunches MAX limit due to quench (safety margin negative) and central detector limit (8 barn over ~437 are useful) . Leads to 7 10 7 ions/bunch.
