namespace Experimental
class CylindricalContainerBuilder : public Acts::Experimental::IDetectorComponentBuilder
#include <Acts/Detector/CylindricalContainerBuilder.hpp>

A dedicated container builder for cylindrical detector containers.

It relies on the detailed implementation of the CylindricalDetectorHelper and allows for DetectorVolume attachment in z/r/phi, such as wrapping of bevelled cylinder objects in z/r


the builder expects a fully consistent set of sub volume builders that will be executed in a chain


allowed BinningValue(s) for the cylindrical container builder are {binZ}, {binR}, {binPhi}, {binZ, binR}, whereas the last option indicates a wrapping setup.

Public Functions

CylindricalContainerBuilder(const Config &cfg, std::unique_ptr<const Logger> logger = getDefaultLogger("CylindricalContainerBuilder", Logging::INFO))

Constructor with configuration arguments.

  • cfg – is the configuration struct

  • logger – logging instance for screen output

virtual DetectorComponent construct(const GeometryContext &gctx) const final

The final implementation of the cylindrical container builder.


gctx – The geometry context for this call


an outgoing detector component
