34 // (Description)
35 // This is a primitive scorer class for scoring cell flux.
36 // The Cell Flux is defined by a track length divided by a geometry
37 // volume, where only tracks passing through the geometry are taken
38 // into account. e.g. the unit of Cell Flux is mm/mm3.
39 //
40 // If you want to score all tracks in the geometry volume,
41 // please use G4PSCellFlux.
