65 // (Description)
66 //
67 // Detector construction for example RE02.
68 //
69 // [Geometry]
70 // The world volume is defined as 200 cm x 200 cm x 200 cm box with Air.
71 // Water phantom is defined as 200 mm x 200 mm x 400 mm box with Water.
72 // The water phantom is divided into 100 segments in x,y plane using
73 // replication,
74 // and then divided into 200 segments perpendicular to z axis using nested
75 // parameterised volume.
76 // These values are defined at constructor,
77 // e.g. the size of water phantom (fPhantomSize), and number of segmentation
78 // of water phantom (fNx, fNy, fNz).
79 //
80 // By default, lead plates are inserted into the position of even order
81 // segments.
82 // NIST database is used for materials.
83 //
84 //
85 // [Scorer]
86 // Assignment of G4MultiFunctionalDetector and G4PrimitiveScorer
87 // is demonstrated in this example.
