This book was released on 2013 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: The work presented herein describes an investigation of four main types of thin film polymer scintillators containing 6Li [lithium-6] for neutron detection: polystyrene containing 6LiF [lithium-6 fluoride] and a preblended fluor mixture comprising 2,5-diphenyloxazole and 1,4-bis(5-phenyloxazol-2-yl)benzene; poly(styrene-co-lithium maleate) containing salicylic acid; poly[styrene-co-lithium maleate-co-2-phenyl-5-(4-vinylphenyl)oxazole]; and poly(styrene-co-lithium 4-vinylbenzoate). A variety of chemical and physical characterizations as well as optical and scintillation characterizations were performed to guide the development of optimized compositions of each type of polymer film. The scintillation performances of optimized compositions of each type of polymer film were calibrated using GS20 lithium glass and evaluated against neutron detection and neutron/gamma-ray discrimination criteria established for radiation portal monitors. Thin films were fabricated 2 inches in diameter over a variety of thicknesses using solution-casting methods. Investigation of polystyrene-based films by photoluminescence and scintillation indicated that the optimum concentration of fluor was 5.00%. Optimum neutron/gamma-ray discrimination was achieved for 50 micrometer thick films containing 10% 6LiF [lithium-6 fluoride]. Two transparent lithium-containing polymers were successfully synthesized: poly(styrene-co-lithium maleate) containing salicylic acid and poly[styrene-co-lithium maleate-co-2-phenyl-5-(4-vinylphenyl)oxazole]. To the author's knowledge, the latter polymer represents the first polymer comprising the matrix, the thermal neutron capture nuclide 6Li [lithium-6], and the fluor that has been synthesized for the purpose of thermal neutron detection. The polymer poly(styrene-co-lithium 4-vinylbenzoate) could not be solvated and decomposed below its melting temperature and was thus considered not useful for this application. The polystyrene-based materials had the greatest light yields whereas the poly[styrene-co-lithium maleate-co-2-phenyl-5-(4-vinylphenyl)oxazole] material had the best neutron/gamma-ray discrimination properties. All three classes of materials can be used to satisfy the detection criteria in the current radiation portal monitor footprint by implementing a multilayer format.
Book Synopsis Lithium Loaded Glass Fiber Neutron Detector Tests by :
Download or read book Lithium Loaded Glass Fiber Neutron Detector Tests written by and published by . This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Radiation portal monitors used for interdiction of illicit materials at borders include highly sensitive neutron detection systems. The main reason for having neutron detection capability is to detect fission neutrons from plutonium. The currently deployed radiation portal monitors (RPMs) from Ludlum and Science Applications International Corporation (SAIC) use neutron detectors based upon 3He-filled gas proportional counters, which are the most common large neutron detector. There is a declining supply of 3He in the world and, thus, methods to reduce the use of this gas in RPMs with minimal changes to the current system designs and sensitivity to cargo-borne neutrons are being investigated. Four technologies have been identified as being currently commercially available, potential alternative neutron detectors to replace the use of 3He in RPMs. Reported here are the results of tests of the lithium-loaded glass fibers option. This testing measured the neutron detection efficiency and gamma ray rejection capabilities of a small system manufactured by Nucsafe (Oak Ridge, TN).
