32 /// Construction of a target material (default = boron) surrounded by a
33 /// casing material (default = water) and a vacuum world (default =
34 /// target and casing fill world). The target + casing is brick
35 /// geometry with fTargetSections defining the number of divisions
36 /// in each dimension. The end sections in each dimension
37 /// is set to the casing. So a fTargetSections = G4ThreeVector(3, 3, 3)
38 /// would be one section of boron and 8 sections of water.
39 /// The idea behind this geometry is just to create a simple geometry that
40 /// scatters and produces a lot neutrons with a minimal number of sections
41 /// (i.e. coarse meshing) such that the contention in operating on
42 /// the atomic hits maps is higher and round-off errors in the
43 /// thread-local hits maps are detectable (printed out in TSRunAction)
44 /// from the sheer number of floating point sum operations.
45 /// Two scorers are implemented: EnergyDeposit and Number of steps
46 /// The energy deposit is to (possibly) show the round-off error seen
47 /// with thread-local hits maps. The # of steps scorer is to verify
48 /// the thread-safe and thread-local hits maps provide the same results.
