Professional Interest:

Simulation of neutron interactions in support of neutron measurement. The implementation of neutron measurement systems usually requires a model to explore alternative designs. In addition, a model can reveal behaviors which must be quantified for the interpretation of measurement results. Typically, the use of MCNP and/or GEANT are sufficient, but occasional use of other models, including the creation of new models, are required. The investigations may be applied to neutron measurement devices and the development of neutron exposure facilities.
