Yasu’s talk

• 110 MeV at the limitation for dynamic range
  • Yunlong will ask an engineer
• Can choose the trigger plane and 4 trigger plane is due to DAQ board with 4 connectors
• Brian suggested to compare both EM shower and electron neutrino energy reconstruction
• Neutrino interaction happens everywhere. So it would be interesting to see if the fiducial cuts would work for Separation (maybe already neural network is doing something though).
• ECAL would provide additional information for mu/electron with combining the FASER since it has a high granularity  and also can observe some hadronic components
• On-axis: electron/muon neutrino with CEPC ECAL and 
• Off-axis: AHCAL + another muon detector behind the AHCAL suggested by Brian?
  • Be able to identify muon neutrino more at the same eta range ?
  • 2026 would be difficult but maybe run4 era 
• Tasks
  • Implement trigger logics
  • neutral hadron and muon background study
  • on-axis ECAL
