INCC is a general purpose neutron coincidence counting program that runs on personal computers running any Microsoft Windows operating system. It is intended for nondestructive passive and active neutron verification applications. Passive neutron verification techniques include calibration curve, known alpha, known multiplication, add-a-source, multiplicity, curium ratio and truncated multiplicity. Active techniques include calibration curve, multiplicity, collar and active/passive. You can use all of these techniques with INCC. Active multiplicity presently determines the neutron multiplication of a uranium item, but does not determine the uranium mass. You can use any of the common coincidence electronics packages currently available.
