?Main tasks
Ultimate goals

• Reliably provide the LHC with the beam required
  for reaching ten (10!) times the nominal
  luminosity
• Optimum use of possibilities offered by the new
  injectors both for the LHC and for other users
  (FT, CNGS...)

• Identify limitations in the existing SPS
• Study and propose solutions
• Design Report in 2010 with cost and planning for
  proposed actions

5
Future LHC beam

• Follow-up closely the LHC upgrade scenarios
• - maybe everything is done in LHC itself...
• - ultimate bunch intensity with 25 ns spacing
• - 3 times ultimate with 50 ns spacing
• PS2 as SPS injector
• injection at 50 GeV/c
• max bunch intensity at 4 GeV 4x1011
• shorter flat-bottom

6
Future CNGS/FT beam

• Different from the present scheme
• - 25 ns bunch spacing
• - 5 batches with 1.1 µs gaps
• - injection at 26 or 50 GeV/c
• Maximum bunch intensity equals ultimate LHC
• Maximum total intensity up to 1x1014

7
Work organization

• Membership
• Inter-departmental study team (AB, AT,TS...)
• A few permanent members
• Co-opted members for different activities
• Linkmen for LHC upgrade and PS2
• ? Reports to PAF and ABMB management
• ? Regular meetings
• ? Web site http//cern.ch/paf-spsu - in
