2. P5 Meeting - Jan. 28-29, 20032 US LHC LHC Upgrades 2010-2015: SLHC Increase Luminosity x 10 to 10 35 Decrease Bunch Crossing Interval x2 to 12.5 ns Detector changes & performance studied for this. >2015: Energy Upgrade? Increase LHC beam energy to 14 TeV (E cm = 28 TeV) Replace LHC dipoles: magnets with a nominal dipole field btw. 16.0 and 16.5 T, would provide 1-2 T safety Equip SPS with superconducting magnets & inject into LHC at 1 TeV Long term future for the program
