Minutes from August 13 meeting

• SB-neutrino oscillation experiments is the main physics motivation for a PD at FNAL that could be available by the end of this decade
• We will like to have a more detailed description of the PD as the means of having a SB at FNAL. This take advantage of the investments already made on NUMI.
• Time scales of final draft of the PD-Physic Studies document by the end of this year, so will like to have analysis finished by End of Oct. In order to achieve this goal we will have a first Mini-Workshop on:
  Monday Sept. 10 Focus on OFF-AXIS issues (tentative)
  
• Enough good work for low energy and booster drive experiments, but can do better for NUMI drive experiments.
  

• Physics motivations
  
  • mu_e appearance
    
  • CP phase
    
  • sign of Delta_m13
• To do the BEST measurement of the list given above, use the already available High, Medium and Low NUMI configurations; but to optimized the physics that we want to do, most also consider:
  • Lower energies when relevant
    
  • OFF-AXIS beams
    
    • ~700 Km baseline
      
    • ~300 Km baseline
      
    • How many detectors at the surface?
      
• Understand systematic issues, therefore realistic beam and detector related systematics most be taken into account:
  
  • For beams we need:
    
    • the different neutrino-type beam components
    • understanding of the near/far spectra, and/or far1/far2 spectra systematics due to
      - Assumptions in the Hadron in production spectra
      - Changes in beam elements
      
    
    
  • For detectors will consider:
    
    • Liquid Argon TPC a la ICARUS
    • Water Cherenkov
    • High granularity detectors: -Steel of ~X_0/4
      -Triangular scintillator with 1cm sides
      
• Changes required in NUMI in order to archive this goals (Currently NUMI is assumed to be able to handle 5X(3*10^13))
  
  • Ground water issues
  • Target/horns
  • Hadron Absorber
  • Shielding around the decay pipe
