- Final inspection of all installed modules: some small issues with lead glass found (chips close to PMT, glass imperfections, cookie bubbles)
  - Bad/broken PMTs being replaced
- Cabling next: will begin in December/January
- Survey ongoing as of meeting, looks good so far
Inventory of 80 uninstalled crystals: plan to make 5x5 TAC + 5x5 and 3x3 prototypes to put in PS test setup in Hall
11 bad crystals packed, ready to be sent back to SICCAS
All signal cables from flash-ADCs to patch panel are ready
Short signal cables arriving (have 1360), students working on testing and labeling
Still missing many dark box cables
HV cables in production
LV cables have been ordered, not clear when will arrive
LV distribution boards: Sasha to meet with engineering group to finalize design
Have all optical fibers for LMS
Sasha met with detector support group to discuss their continuing involvement (soldering wires, testing PMT dividers, gluing fibers to crystals,...)
PMT divider testing to start: working on test setup (expect to go through ~30/day?)
LMS installation also December/January
- FCAL group working on plexiglas for lead glass LMS
3 undergraduate students expected to go to DNP meeting in Hawaii
Simon presented a first look at the impact of adding a GEMTRD at the exit of the solenoid
- Also added placeholder for inner-TOF detector
