38 | // This is a primitive scorer class for scoring Surface Flux. |

39 | // Current version assumes only for G4Tubs shape, and the surface |
---|
40 | // is fixed on inner plane of the tube. |
---|
41 | // |
---|
42 | // Surface is defined at the innner surface of the tube. |
---|
43 | // Direction R R+dR |
---|

---|
45 | // 1 IN ->| | |
