14:00 → 14:10 DSL report

Pre-TDR Assignments:
- Sam: neutron efficiency
- Tianhao: Simulation vs. CMS data, impact of tile uniformity
- Maria: intro/overview of design optimization
- UIUC: Updates to muon ID and muon plots
- Leszek: updates to sampling fraction and geometry description. Update into plots to include neutrons / muons and mean energy for the tail catcher region
- CTU (Sasha/alexander/Subadip): Upate plots similar to DAC presentation to show the position resolution (5x5, 10x10, 15x15) and the Delta Rxy distribution.
- Yevhenia: nHCAL performance evaluation and tests

I have a version of the pre-TDR with only the nHCAL that we can use to draft before pushing our updates to the official epic pre-TDR document:
