Brief introduction 10mSpeaker: Hidetoshi Otono (Kyushu University (JP))
ECAL could be commissioning for KEK beam line in May or June
- Need to discuss Jianbei, May-June would be busy. Summer is preferred.
- USTC takes care of local commissioning locally, then ship it to Japan?
- Wataru mentions we need experts for electronics in person at KEK
- Needs input: the earliest date for the shipment from USTC to Japan
Veto system
- Scintillator would not be a big problem.
- How to combine trigger with HCAL. We can not use the current FASER logic.
- Need inputs: the existing HCAL trigger logic, as well as ECAL one.
- Allowed distance? Between detector and electronics. The cables are about 3 m.
- Need to ask an electronics expert it could be extended. Also, their sizes.
MISC
- In-person: the end of February or 1st week of March?
- At EHN1, which is the commissioning area at CERN SPS area, the horizontal muon “beam” is available.
- Though normally, test with cosmic
- Next online meeting: 6th February, 23rd 10pm JST/ 9pm CST/2pm CET

Simulation study 20mSpeaker: Yasuhiro Maruya (Institute of Science Tokyo (JP))
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
- 110 MeV at the limitation for dynamic range
