addCylindricalTrackingVolumeToCaloNode()

void ActsTrk::CaloBlueprintNodeBuilder::addCylindricalTrackingVolumeToCaloNode ( Acts::Experimental::CylinderContainerBlueprintNode & containerNode, const std::string & volumeName, const std::vector< std::shared_ptr< Acts::Surface > > & surfaces, int layerIndex, const bool & isDisc ) const

private

addCylindricalTrackingVolumeToCaloNode adds a cylindrical tracking volume to the calo node.

It takes as input the container node, the calo dimensions map, the name of the volume and the vector of surfaces to be added to the volume. It creates a new CylinderContainerBlueprintNode in the container node, then creates a new Acts::TrackingVolume with the appropriate dimensions. Finally it adds the Acts::CylinderSurface to that Acts::TrackingVolume, then adds the tracking volume to the container node.

The first maps each calo sampling to a vector of surfaces (initially empty) The second maps each calo sampling to a vector of CaloDetDescrElements The second map is filled by looping over all DDE in the CaloDetDescrManager and adding each DDE to the vector corresponding to its sampling in the map

generateCylinderSurface generates a cylindrical surface for a given set of parameters.

To do this it calculates the radius and length of the cylinder, then shifts it in Z to the midpoint of the Z values used to build it. It then creates the Acts::CylinderSurface and returns it via a shared pointer.

generateCylinderSurfaces generates cylindrical surfaces for each calo sampling.

It does this for cylindrical layers by scanning in Z, for each Z finding the average radius of the cells in a phi ring If the average radius changes by more than a tolerance value (m_radiusTolerance), a new cylinder surface is created. The surfaces are added to the relevant vector of surfaces in the caloSampleSurfaceMap.
