azaree_lintereur All are welcome to an invited seminar by Dr. Azaree Lintereur, from the Nuclear Engineering Program at the University of Utah. Dr. Lintereur is an Assistant Professor in the Department of Civil and Environmental Engineering. The title is: “Neutron Detection: Applications and Challenges in Nuclear Safeguards.” The seminar will be from 3:00 to 4:00 p.m. on Wednesday December 10, in WEB L102. There will be light refreshments afterwards.

Neutron Detection: Applications and Challenges in Nuclear Safeguards:
A variety of techniques exist for the non-destructive analysis of samples in nuclear safeguards. In scenarios where external and self-shielding are of concern neutron detection can be a viable sample characterization method. There are various neutron detection options, each of which provides different information and presents unique challenges. One of the most challenging neutron detection measurement methods is neutron multiplicity counting. Neutron multiplicity counting is used to assay samples that contain potentially unknown amounts (and forms) of special nuclear materials. The measurements are capable of precisely identifying up to three unknown parameters, allowing for advanced sample characterization. Neutron multiplicity counting has traditionally been performed using 3He as the detection media; however, due to recent shortages in 3He alternative options are being explored. This seminar will cover an overview of neutron detection for safeguards applications and the latest research in the development of a 3He alternative multiplicity counter.

Dr. Azaree Lintereur recently joined the Nuclear Engineering Program in the Department of Civil and Environmental Engineering as an Assistant Professor. Dr. Lintereur received her Ph.D. in Nuclear and Radiological Engineering from the University of Florida, where she also earned a Master’s degree with an emphasis on Medical Physics. Dr. Lintereur’s graduate research included work with wide-band gap semiconductors for room temperature gamma ray spectroscopy and 3He alternatives for neutron detection. Prior to joining the faculty at the University of Utah Dr. Lintereur was a postdoctoral research assistant at Pacific Northwest National Laboratory. Her research at Pacific Northwest National Laboratory focused on 3He alternatives for neutron detection, and pulse shape discrimination methods for neutron-gamma ray sensitive materials. Dr. Lintereur is currently leading the effort to establish a radiation detection track at the University of Utah. Her research interests include radiation detector development, nondestructive assay techniques, and 3He alternative technologies.
