Agenda

  1. Writeups needed for the pre-brief materials packet - see below
  2. Tim's updated tagger hall drawings
  3. Relative placement of fixed array and microscope - Richard, Franz, Tim
  4. Resolution on tagger pole shape - Jim, Yang
  5. Remaining simulation studies needed for review - Richard
  6. Progress on simulation of the collimators - Sascha



List of documents for review pre-brief package

  1. The general consensus was that we should take chapter 4 in the TDR version 4 and re-write it and then use this as the core of the pre-brief material.
  2. A short document which summarized the recommendations from the last review and how they were resolved.
  3. A drawing package for the magnet needs to be provided.
  4. An update of the preliminary spec should be given.
  5. Yang's note on the TOSCA and transport studies should be included.
    • Yang's report
    • Dan Sober has agreed to work on improving this document.
  6. A description of the present status of the fixed hodoscope.
  7. The June R+D note on the microscope
  8. The pair spectrometer proposal with a few updated.
  9. Plan for what we want to study with diamonds.
  10. Simulations - Alex
