Struct Acts::DD4hepLayerBuilder::Config

struct Config

nested configuration struct for steering of the layer builder

Public Members

BinningType bTypePhi = equidistant

the binning type of the contained surfaces in phi (equidistant/arbitrary)

BinningType bTypeR = equidistant

the binning type of the contained surfaces in r (equidistant/arbitrary)

BinningType bTypeZ = equidistant

the binning type of the contained surfaces in z (equidistant/arbitrary)

std::vector<dd4hep::DetElement> centralLayers

the DD4hep::DetElements of the layers of the central volume (barrel)

Note

if the current volume has no layers this parameter will not be set

std::string configurationName = "undefined"

string based identification

double defaultThickness = UnitConstants::fm

In case no surfaces (to be contained by the layer) are handed over, the layer thickness will be set to this value.

Attention

The default thickness should be set thin enough that no touching or overlapping with the next layer can happen.

Note

Layers containing surfaces per default are not allowed to be attached to each other (navigation will bail at this point). However, to allow material layers (not containing surfaces) to be attached to each other, this default thickness is needed. In this way, the layer will be thin (with space to the next layer), but the material will have the’real’ thickness.

std::shared_ptr<const LayerCreator> layerCreator = nullptr

layer creator which is internally used to build layers

std::vector<dd4hep::DetElement> negativeLayers

the DD4hep::DetElements of the layers of the negative volume (negative endcap)

Note

if the current volume has no endcaps or no layers this parameter will not be set

std::vector<dd4hep::DetElement> positiveLayers

the DD4hep::DetElements of the layers of the positive volume (positive endcap)

Note

if the current volume has no endcaps or no layers this parameter will not be set
