0036 // Comments
0037 //
0038 // This example intends to show how to use importance sampling and scoring
0039 // in the mass (tracking) geometry.
0040 // A simple geometry consisting of a 180 cm high concrete cylinder
0041 // divided into 18 slabs of 10cm each is created.
0042 // Importance values are assigned to the 18 concrete slabs in the
0043 // detector construction class for simplicity.
0044 // Pairs of G4GeometryCell and importance values are stored in
0045 // the importance store.
