0027 /// \brief Definition of the TSDetectorConstruction class
0028 //
0029 //
0030 //
0031 //
0032 /// Construction of a target material (default = boron) surrounded by a
0033 ///     casing material (default = water) and a vacuum world (default =
0034 ///     target and casing fill world). The target + casing is brick
0035 ///     geometry with fTargetSections defining the number of divisions
0036 ///     in each dimension. The end sections in each dimension
0037 ///     is set to the casing. So a fTargetSections = G4ThreeVector(3, 3, 3)
0038 ///     would be one section of boron and 8 sections of water.
0039 /// The idea behind this geometry is just to create a simple geometry that
0040 ///     scatters and produces a lot neutrons with a minimal number of sections
0041 ///     (i.e. coarse meshing) such that the contention in operating on
0042 ///     the atomic hits maps is higher and round-off errors in the
0043 ///     thread-local hits maps are detectable (printed out in TSRunAction)
0044 ///     from the sheer number of floating point sum operations.
0045 /// Two scorers are implemented: EnergyDeposit and Number of steps
0046 ///     The energy deposit is to (possibly) show the round-off error seen
0047 ///     with thread-local hits maps. The # of steps scorer is to verify
0048 ///     the thread-safe and thread-local hits maps provide the same results.
