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