Special nuclear materials and other radioactive materials have been long recognized as a major threat to national and global security. Detection of illicit nuclear materials in transit is a particularly pressing problem which can be addressed by both passive and active detection. In all cases, advanced radiation detectors and measurement methods are needed, with high efficiency and specificity that can suppress the ubiquitous and variable radiation background. I will describe our recent efforts to develop novel heterogeneous scintillators suitable for detection of neutrons at a variety of energies, in which we engineer the detector properties from a combination of fundamental material characteristics and geometric design. I will further describe the applications of these detectors in active interrogation systems, including the detection of beta-delayed signatures of nuclear fission as a means to detect illicit nuclear material and fast neutron transmission radiography for improved material imaging and identification.
Igor Jovanovic received his BS/MS in Electrical Engineering from the University of Zagreb, Croatia in 1997 and PhD in Nuclear Engineering from the University of California, Berkeley in 2001. He was a staff physicist at Lawrence Livermore National Laboratory in the period of 2002-2007, leading a variety of projects related to ultrafast laser science and technology, stockpile stewardship, fusion technology, and advanced radiation detectors. He was with Purdue University (2007-2010) and with Penn State (2010-2015), where he also held the Bashore Career Development Professorship. Since 2016 he is a Professor in the Department of Nuclear Engineering and Radiological Sciences and the Applied Physics Program at the University of Michigan, director of the Neutron Science Laboratory, and leader of the Applied Nuclear Science Group. He conducts research in radiation detection for nuclear security and intense laser science with support of DOE, DHS, NSF, DTRA, and DARPA. Dr. Jovanovic is a recipient of the DARPA Young Faculty Award and the DHS Nuclear Forensics Junior Faculty Award.
