60 // (Description)
61 //
62 // Detector construction for example RE02.
63 //
64 // [Geometry]
65 // The world volume is defined as 200 cm x 200 cm x 200 cm box with Air.
66 // Water phantom is defined as 200 mm x 200 mm x 400 mm box with Water.
67 // The water phantom is divided into 100 segments in x,y plane using
68 // replication,
69 // and then divided into 200 segments perpendicular to z axis using nested
70 // parameterised volume.
71 // These values are defined at constructor,
72 // e.g. the size of water phantom (fPhantomSize), and number of segmentation
73 // of water phantom (fNx, fNy, fNz).
74 //
75 // By default, lead plates are inserted into the position of even order
76 // segments.
77 // NIST database is used for materials.
78 //
79 //
80 // [Scorer]
81 // Assignment of G4MultiFunctionalDetector and G4PrimitiveScorer
82 // is demonstrated in this example.
