1. Review schedule and list of "deliverables"
   • Elton summarized this task as part of the 12 GeV project and the need to show progress and complete in the scheduled timeframe. According to the P6 project schedule, this activity was to be completed last year. Based on various circumstances we are already behind. The goal is for a complete prototype by May of this year.
2. First article testing (Carl and Yi)
3. Mechanical cooling (Jim)
4. Temperature compensation (Jack)
5. Preamp-summing (Fernando)
   • Received files from Chuck, but needs to upgrade software to read them in (almost complete). The files will contain boundaries for laying out the electronics.
   • Hamamatsu board (with summed output) ready to ship out next week
   • Boards with 16-cell readout for testing should be ready soon and can be made available to Yi/Carl and USM.
   • Specification list must include: dynamic range, linearity
6. Discussion
