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 preliminary recommendations

• Extensive consolidation
• Phase 2 for PS magnets gt 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
