- Actual blocks with current design, instead of just single huge donuts volume
- Realistic north-south gap
- Added Al mounting plate
- Adjusted Z locations according to Joshua's updated number
- Get rid of active insert, and replaced with U shaped "beam pipe protectors"
- Homogeneous material implementation
- epic/configration/fecal.yml - confignration file for fEcal alone
- epic/compact/ecal/forwardEcal.xml - provides some global parameters & define hits
- epic/src/forwardEcal_geo.cpp - implementing Homogeneous geometry
- Hits defined as System(102 for fEcal, 8 bit), NorthSouth(1bit), BlockRow(6bit), BlockColumn(5bit), X(2bit) and Y(2bit) for 4x4 towers in a block
- W powder + ScFi implementation
- epic/configration/fecal_scfi.yml - confignration file for fEcal alonem ScFi version
- epic/compact/ecal/forwardEcalScFi.xml - provides some global parameters & define hits
- epic/src/forwardEcalScFi_geo.cpp - implementing ScFi geometry
- BirksConsttant=0.126*mm/MeV for ScFi core
- Hits defined as System(102 for fEcal, 8 bit), NorthSouth(1bit), BlockRow(6bit), BlockColumn(5bit), TowerCol(2bit), TowerRow(2bit), FiberCol(5bit), FiberRow(5bit) and fake X(1bit) and Y(1bit)
- Issue with dd4hep VolumeManager? Extra slow (> 30min startup)
- Discussion at EPIC help desk, which continues here
- Question posted at DD4Hep Github
- Geant4RegexSensitivesConstruction causes startup to take > 30min
- A temporally fix with fake CartesianGridX which brings down startp time to ~3min (don't ask me why and how this works)
- epic/src/forwardEcalMap.h - helper functions for fEcal mapping and decoding
