Novel Polycrystalline Scintillators for Nuclear Non-Proliferation
Proliferation of the weapons of mass destruction such as nuclear weapons is a serious threat in the world today. Prevention of the spread of nuclear weapons has reached a state of heightened urgency in recent years. Scintillator based gamma-ray spectrometers are an important tool in checking the proliferation of the nuclear weapons. The performance of the current radioisotope identifiers is limited by the characteristics as well as cost of scintillators available at present. The goal of the proposed project is to investigate new scintillation materials that can be produced with excellent optical and scintillation properties using a low cost fabrication approach. Increased flexibility, significantly lower cost as well as high performance can be expected from the proposed technology. The Phase I project was aimed at demonstrating the feasibility of producing high performance scintillators using a low-cost manufacturing method. The fabrication processes were explored and the scintillators produced were evaluated. The Phase II project will involve detailed exploration of the fabrication processes to produce polycrystalline scintillators with high optical quality in large sizes. Evaluation of scintillation properties as well as gamma and neutron detection performance will also be conducted. Commercial Applications and Other Benefits: Over and above use in nuclear non-proliferation, the new detectors will be commercially applicable to medical imaging, NDE, and materials analysis. They will also be useful in nuclear, high energy and space physics experiments.
