Measurement and simulation of cosmic rays effects on neutron multiplicity counting

Additional verification of MCNP6 was given by comparison of particle production rates to other publications, increasing confidence in MCNP6׳s use as a tool to lower the limit of detection. MCNP6 was then used to find particle and source information that would be difficult to detect experimentally. The coincidence count contribution was broken down by particle type for singles, doubles, and triples rates. The coincidence count contribution was broken down by source, from(a,n), spontaneous fission, and cosmic rays, for each multiplicity.
