Jack Linkous unveils fissionable material imaging at CVT workshop

On October 16, 2015, during the Consortium for Verification Technology (CVT) workshop at University of Michigan, Jack Linkous (a senior RADIANS team member and CVT graduate fellow) demonstrated a new method to image sources of neutrons from fissionable materials.

Jack’s technique for imaging fissionable material exploits the dynamics of fission chain-reactions to discriminate between spontaneous fission neutron sources and sources of neutrons from self-multiplying special nuclear material (SNM).¬† Using the recent RADIANS experiments with SNM at the Nevada Test Site, Jack showed he could distinguish images of weapons-grade plutonium from images of californium-252.

Jack worked with Dr. Jason Newby of Oak Ridge National Laboratory (ORNL) and Prof. John Mattingly of NCSU to develop and implement his new neutron imaging technique.
