工作内容:集中力量验证reference detector方案，给出初步结果
Minutes: Linghui, Yong
-
Current status of crystal ECAL simulation studies: Yong
- ECAL detector layout
- Long crystal bars with double-ended readout
- Crossed placement in alternating layers
- Geant4 stand alone simulation
- Digitiser for crystal cubes and scintillator tiles (done)
- Digitiser for long crystal bars, esp. timing at two ends (done, but needs further validation)
- CEPCsoft
- Implemented two layouts of crystal ECAL geometry: long bars, cubes
- Event display with “Druid”
- CEPCSW
- Basic sub-detectors already implemented in DD4HEP
-
Discussions on the efforts/plans for CEPCSW: Bo, Gang, Linghui, Shengsen, Yong, Yuexin
- ECAL geometry: first priority
- Implementation of crystal ECAL with long bars
- Studies of a single long crystal bar
- Basis for digitisation; needs solid validation
- Full simulation in Geant4 with optical photon processes
- Develop test stands and perform measurements for comparision with the full simulation
- Multi-hits
- in a single crystal bar
- To be checked
- Digitization: needs further discussions
- PFA performance
- Dependency on the tracker performance
- Matching performance of charged tracks in the tracker and ECAL
- Energy information for PFA
- Software compensensation
- Dual readout for crystals
- PandoraPFA
- Tuning of calibration constants
- Validation with MC truth
- Calibration studies for CEPC calorimeters (Stathes’ proposal)
- To prepare MC samples and provide information that he needs
- Need further detailed discussions: Yong, Hongbo, Stathes
-
Action items
- G4 full simulation of a long crystal bar: Baohua, Yong (1~2 weeks)
- Preparation of test stands for crystals: Baohua, Yong (~4 weeks)
