Detailed Description

Detector construction class to define materials and geometry. The calorimeter is a box made of a given number of layers. A layer consists of an absorber plate and of a detection gap. The layer is replicated.

Four parameters define the geometry of the calorimeter :

• the thickness of an absorber plate,
• the thickness of a gap,
• the number of layers,
• the transverse size of the calorimeter (the input face is a square).

In ConstructSDandField() sensitive detectors of G4MultiFunctionalDetector type with primitive scorers are created and associated with the Absorber and Gap volumes. In addition a transverse uniform magnetic field is defined via G4GlobalMagFieldMessenger class.
