NE Colloquium. Patricia Schuster - "Science and Security Applications of Organic Scintillator Radiation Detectors"
Radiation detectors are instrumental for identifying, characterizing, and imaging radiation and radioactive sources in many areas including nuclear security, nonproliferation, safeguards, and basic science research. Organic scintillator materials are particularly useful as radiation detectors because of their ability to detect neutrons and gamma rays simultaneously and discriminate between them, but they face performance limitations for neutrons below 1 MeV. In this talk, Dr. Schuster will introduce several systems that employ organic scintillators, including the LANL LANSCE Chi-Nu array for basic science measurements and the CONFIDANTE coded aperture imager for zero-knowledge warhead verification. Then she will share her work to better understand the physical processes that govern performance limitations, including experimental characterization of the scintillation dependence on particle type, interaction direction, and temperature. Finally, Dr. Schuster will share her perspectives on how radiation detection technologies stand to gain from leveraging new technologies such as 3D printing, multi-model detection, and sensor fusion.
