New CLIC ECal in DD4hep

The way detector models are defined is quite different between Mokka and DD4hep. DD4hep provides representations of all TGeo shapes and means to place them in a hierarchy of detector elements with additional information, and this is the core feature of DD4hep.

Current ECal implementations

Current implementations can be found in:

• ilcsoft/v01-17/gear/v01-03/example/gear_ILD_o1_v05.xml or gear_TGeoILD00.xml
• ilcsoft/v01-17/Clupatra/v00-09-01/examples/gear_CLIC_CDR.xml

Prototype implementations of the ECal in DD4hep

• CLICSiD (CLIC Silicon Detector CDR by C.Grefe) - contains the ECal parameters
• ILDEx (ILD Detector Toy model by F. Gaede) - does not contain any ECal components

The CLICSiD example in the Root's GL viewer:

Implementing ECal in the ILD model

As a first step, one can copy the ECal components from the CLICSiD to the existing ILDEx model.
