Fabrication Of Specialized Scintillators For Nuclear Security Applications, Cordell James Delzer
Doctoral Dissertations
Radiation detectors are important for a variety of fields including medical imaging, oil drilling, and nuclear security. Within nuclear security, they can serve a multitude of purposes whether that be imaging, localization, isotopic identification, or even just activity measurement. Even without directly seeing a nuclear material it is often able to notice their existence without a detector. Scintillators make up an important part of these detectors due to their large intrinsic efficiency, low cost, large volume, and relatively low upkeep. Due to the importance of the large number of purposes these scintillators may be used for, it can often be …

In the field of nuclear security, the ability to detect neutrons is a critical part of the prevention of the smuggling of illicit nuclear materials. The use of dual-mode detector would drastically reduce the number of passive detector systems necessary to meet the detection needs of the nuclear security industry. Li-containing scintillators have been researched for over 70 years; however, relatively few efficient dual-mode detector materials have been discovered. The currently available Li-containing scintillators are relatively low density, very difficult to grow, and highly hygroscopic. These limitations make the wide-spread use of Li-containing scintillators as dual-mode detectors inefficient and expensive. …
