buildReadOutElements()

StatusCode MuonGMR4::MdtReadoutGeomTool::buildReadOutElements ( MuonDetectorManager &  mgr )

finaloverride

The keys should be formatted like <STATION_NAME>_<MUON_CHAMBERTYPE>_etc. The <MUON_CHAMBERTYPE> also indicates whether we're dealing with a MDT / TGC / CSC / RPC chamber If we are dealing with a MDT chamber, then there are 3 additional properties encoded into the chamber <STATIONETA>_<STATIONPHI>_ML

Skip the endcap chambers

Load first tube etc. from the parameter book table

Chamber dimensions are given from the GeoShape

loadDimensions()

StatusCode MuonGMR4::MdtReadoutGeomTool::loadDimensions ( FactoryCache &  facCache, MdtReadoutElement::defineArgs &  args  ) const

private

Loads the chamber dimensions from GeoModel.

The trapezoid defines the length of the chamber including the extra material stemming from the faraday cache etc.

Loop over the child nodes of the full mdt tube layer volume to pick the ones representing the tubeLayer – their logical volume is callded TubeLayerLog. The node right before the child volume is the associated transform node

Next check all tubes whether they're made up out of air or not. If yes, then there's no tube at this place and add the corresponding has hto the list.

Check for the endplug volumes

Either all tubes have an endplug or none
