37 // Comments
38 //
39 // This example intends to show how to use importance sampling and scoring
40 // in the mass (tracking) geometry.
41 // A simple geometry consisting of a 180 cm high concrete cylinder
42 // divided into 18 slabs of 10cm each is created.
43 // Importance values are assigned to the 18 concrete slabs in the
44 // detector construction class for simplicity.
45 // Pairs of G4GeometryCell and importance values are stored in
46 // the importance store.
47 // Scoring is carried out by the multifunctional detector (MFD) and
48 // sensitive detectors
49 //
50 // Alex Howard (alexander.howard@cern.ch):
51 // 22/11/13: Migrated to the new MT compliant design which moves the
52 // biasing process to the physicslist constructor - here
53 // via the modular physicslists
