  1. SCENARIOS & RECOMMENDATIONS PAF views 19, December 2005 PAF summary

  2. Summary of physics guidelines • LHC: “Maximize integrated luminosity” • 2007-2015 • (L1) - Minimize turn-around time by improving reliability / minimizing duration of stops • (L2) – Remove bottle-necks towards ultimate luminosity • Sketch scenarios for SLHC and prepare for it • 2015-2020 • (SL) - Implement SLHC • (DL) - Prepare for DLHC • Neutrino physics • 2006-2010 • Pursue development for b-beam + super-beam (bB) and n factory (nF) • Depending on physics and outcome of technical developments, elaborate a proposal for a n facility at CERN • Other physics (physics with kaons (k), muons (m), heavy-ions, antiprotons and nuclear physics (NP)) • Decide upon the accelerators set-up based on the needs of priorities 1 & 2 • Adapt the experiments to the capabilities of the resulting accelerators PAF summary

  6. PAF preliminary recommendations • Extensive consolidation • Phase 2 for PS magnets => strong nc magnet team • SPS magnets • Other items (to be analysed later) • Reduction of SPS impedance (kickers + ?) • Construction of Linac4 • Aggressive R & D on: • High field magnets (LHC IR magnets, DLHC dipoles…) • Fast cycling superconducting magnets • Superconducting RF • High power targets • Strengthening of teams involved in: • High power RF • Accelerator design (RCS, FFAG ?) • Radio-protection / environmental impact studies PAF summary
