36 // Comments
37 //
38 // This example intends to show how to use importance sampling and scoring
39 // in the mass (tracking) geometry.
40 // A simple geometry consisting of a 180 cm high concrete cylinder
41 // divided into 18 slabs of 10cm each is created.
42 // Importance values are assigned to the 18 concrete slabs in the
43 // detector construction class for simplicity.
44 // Pairs of G4GeometryCell and importance values are stored in
45 // the importance store.
