At SLAC, the meeting will be held in the Sierra Room (next to Director's Office in Central Lab)
Call in info: 510-665-5437. Meeting id is 7752

1.  Snowmass planning: MDI --  Detector WG on IPBI, IR&Bkgds; Accelerator WG4 on Beam Delivery Systems
          - discuss plans for "MDI" sessions, scheduled talks and mini-Working Groups on specific topics
             and questions.  In context of 3 flavors of WGs:  Detector, Accelerator and Detector Concept
          - see Snowmass program
          - send suggestions for talks, discussions, organization to Mike Woods

        Tentative IPBI schedule at Snowmass
        WG4 schedule at Snowmass

2.  References for Snowmass:

• MDI questions from WWS to be addressed at 1:30 session on 8/17
• MDI Panel Report
• ILC Beam Delivery System Pre-Snowmass Baseline Configuration Document (DRAFT)
• 2-mrad and 20-mrad extraction line configs to be used for Snowmass studies
            - optics decks for 2mrad and 20mrad from Yuri Nosochkov
            - GEANT files for 2mrad and 20mrad from Takashi Maruyama;    
                     (GEANT file format here)
• Guinea-Pig files of IP collision particle distributions that can be used for Snowmass studies:

• photons, disrupted electrons, radiative Bhabhas:  files from Takashi
  Notes:  - beamsstrahlung photons are in *photon.dat
              - disrupted electrons are in *beam1.dat
              - radiative Bhabhas are in *compt.dat
              - pairs are in *pair*.dat
              - the 4 ILC collision parameter sets considered here can be distinguished 
                by n (nominal), p (low beam power), q (low charge option), y(large
                spot), h (high lumi option) in the naming of the .dat files
• new 1 TeV high lumi parameters from Andrei Seryi:
       Case 26:  i) head-on and ii) 100-nm vertical offset
       Case 27:  i) head-on and ii) 100-nm vertical offset
  There are single output files (charged beam and photons) and also high statistics results (500 runs) for accurate evaluation of tails of the E distribution of the charged beams.
• other GP files from Andrei Seryi

3.  Moffeit's quick look at beam distributions for 2mrad (pdf);
          - horizontal spotsize at Compton IP is 8mm rms??  !!  too large to get reasonable Compton signal
          - similar plots for 20mrad extraction line (pdf)
