- Time: 9:30 EST
- Place: EVO and ESNET (with telephone bridge)
- Connecting: instructions are here
- Present:
Agenda
- Writeups needed for the pre-brief materials packet - see below
- Tim's updated tagger hall drawings
- Relative placement of fixed array and microscope - Richard, Franz, Tim
- Resolution on tagger pole shape - Jim, Yang
- Remaining simulation studies needed for review - Richard
- Progress on simulation of the collimators - Sascha
List of documents for review pre-brief package
- 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.
- A short document which summarized the recommendations from the last review and how they were resolved.
- A drawing package for the magnet needs to be provided.
- An update of the preliminary spec should be given.
- Yang's note on the TOSCA and transport studies should be included. Dan Sober has agreed to work on improving this document.
- A description of the present status of the fixed hodoscope.
- The June R+D note on the microscope
- The pair spectrometer proposal with a few updated.
- Plan for what we want to study with diamonds.
