    • New version slightly better signal-to-background
      • Larger impact of new code on 3π0 background compared to η→2γ peaking background
  • Sasha installed 4 new module assemblies on the PS arm in the Hall we use for checking modules
    • Plan to fabricate another plate used for assembling a second set of modules to get ready for checking in the hall
  • Crytur indicated that they could start producing crystals in February
  • PMTs continue arriving at lab; diameter checking continues
  • Planning to restart module construction in December
    • Help from Tim's group will continue
    • Discussions regarding help from detector support group ongoing
    • Phil may be able to provide students to help out next summer
    • Bill B. (GWU) will also check if can provide student manpower, also can do PMT divider checks at GWU
  • PMT divider redesign still not finalized, would be nice to do beam test during upcoming SRC experiment
  • Some discussion of building a 5x5 lead tungstate prototype
