64// (Description)
65//
66// Detector construction for example RE02.
67//
68// [Geometry]
69// The world volume is defined as 200 cm x 200 cm x 200 cm box with Air.
70// Water phantom is defined as 200 mm x 200 mm x 400 mm box with Water.
71// The water phantom is divided into 100 segments in x,y plane using replication,
72// and then divided into 200 segments perpendicular to z axis using nested
73// parameterised volume.
74// These values are defined at constructor,
75// e.g. the size of water phantom (fphantomSize), and number of segmentation
76// of water phantom (fNx, fNy, fNz).
77//
78// By default, lead plates are inserted into the position of even order segments.
79// NIST database is used for materials.
80//
81//
82// [Scorer]
83// Assignment of G4MultiFunctionalDetector and G4PrimitiveScorer
84// is demonstrated in this example.
85// -------------------------------------------------
86// The collection names of defined Primitives are
87// 0 PhantomSD/totalEDep
