class DetectorConstruction_v1 : public G4VUserDetectorConstruction, public MsgService, public Gaugi::PropertyService

Defines the full detector geometry for the simulation.

This class implements the G4VUserDetectorConstruction interface to build the Lorenzetti detector (calorimeters) using Geant4 geometry primitives. It manages materials, logical volumes, and placements for both horizontal and vertical calorimeter plates.

Properties:

• UseMagneticField: Toggle global magnetic field (2 Tesla).

• CutOnPhi: Restrict the detector to a phi wedge (used for debugging/visualization).

Constructs the horizontal plates of a calorimeter module (Barrel).

Creates a “sandwich” structure of absorber, gap, and absorber layers arranged radially (for cylindrical/barrel geometry).

Parameters:

• worldLV – Mother logical volume.

• name – Unique name for the volume.

• defaultMaterial – Envelope material (usually Vacuum).

• absorberMaterial – Absorber material (e.g., Pb, Fe).

• gapMaterial – Active material (e.g., LAr, Scintillator).

• nofLayers – Number of repeating layers.

• absoThickness – Thickness of the absorber plate.

• gapThickness – Thickness of the active gap.

• calorRmin – Inner radius.

• calorZ – Total length in Z.

• center_pos – Center position (displacement).

• region – G4Region associated with this detector part.
