Detailed Description

DetectorElement class implementation for DD4hep geometry.

DetectorElement plugin for DD4hep detector elements. DD4hep is based on TGeo shapes, therefore the DD4hepDetectorElement inherits from TGeoDetectorElement. The full geometrical information is provided by the TGeoDetectorElement. The DD4hepDetectorElement extends the TGeoDetectorElement by containing a segmentation for the readout.

Constructor & Destructor Documentation

Acts::DD4hepDetectorElement::DD4hepDetectorElement	(	const dd4hep::DetElement	detElement,
		const std::string &	axes = "XYZ",
		double	scalor = 1.,
		bool	isDisc = false,
		std::shared_ptr< const ISurfaceMaterial >	material = nullptr,
		std::shared_ptr< const DigitizationModule >	digitizationModule = nullptr
	)

Constructor

Parameters

detElement	The DD4hep DetElement which should be linked to a surface
axes	is the axis orientation with respect to the tracking frame it is a string of the three characters x, y and z (standing for the three axes) There is a distinction between capital and lower case characters : capital -> positive orientation of the axis lower case -> negative oriantation of the axis

Example options are:

• "XYZ" -> identical frame definition (default value)
• "YZX" -> node y axis is tracking x axis, etc.
• "XzY" -> negative node z axis is tracking y axis, etc.

  Parameters

  scalor	is the scale factor for unit conversion if needed
  isDisc	in case the sensitive detector module should be translated as disc (e.g. for endcaps) this flag should be set to true

  Note

  In the translation from a 3D geometry (TGeo) which only knows tubes to a 2D geometry (Tracking geometry) a distinction if the module should be described as a cylinder or a disc surface needs to be done. Since this information can not be taken just from the geometry description (both can be described as TGeoTubeSeg), one needs to set the flag 'isDisc' in case a volume with shape TGeoTubeSeg should be translated to a disc surface. Per default it will be translated into a cylindrical surface.

  Parameters

  material

  Possible material of detector element
