0044 /// - the thickness of an absorber plate,
0045 /// - the thickness of a gap,
0046 /// - the number of layers,
0047 /// - the transverse size of the calorimeter (the input face is a square).
0048 ///
0049 /// In ConstructSDandField() sensitive detectors of CalorimeterSD type
0050 /// are created and associated with the Absorber and Gap volumes.
0051 /// In addition a transverse uniform magnetic field is defined
0052 /// via G4GlobalMagFieldMessenger class.
