38 // (Description)
39 // This is a primitive scorer class for scoring Surface Current.
40 // Current version assumes only for G4Box shape, and the surface
41 // is defined at the -Z plane of the box.
42 // The current is given in the unit of area.
43 // e.g. (Number of tracks)/mm2.
44 //
45 // Surface is defined at the -Z surface.
46 // Direction -Z +Z
47 // 0 IN || OUT ->|<- | fCurrent_InOut
48 // 1 IN ->| | fCurrent_In
49 // 2 OUT |<- | fCurrent_Out
50 //
51 //
52 // Created: 2005-11-14 Tsukasa ASO, Akinori Kimura.
53 // 17-Nov-2005 T.Aso, Bug fix for area definition.
54 // 31-Mar-2007 T.Aso, Add option for normalizing by the area.
55 // 2010-07-22 Introduce Unit specification.
56 // 2020-10-06 Use G4VPrimitivePlotter and fill 1-D histo of kinetic energy (x)
57 // vs. Surface Current * track weight (y) (Makoto Asai)
