It was designed for the reactor operating power at 1.2 MW. The purpose of the system is for an elemental and isotopic analytical. In 2016, the PGNAA facility will be developed to reduce the leakage and background of neutrons and gamma radiation at the sample and detector position. In this work, the designed condition of these facilities is carried out based on the Monte Carlo method using MCNP5 computer code. The conditions with different modification materials, thicknesses and structure of the PGNAA facility, including gamma collimator and radiation shields of the detector, are simulated, and then the optimal structure parameters with a significantly improved performance of the facility are obtained. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=MCNP%20simulation" title="MCNP simulation">MCNP simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=PGNAA" title=" PGNAA"> PGNAA</a>, <a href="https://publications.waset.org/abstracts/search?q=Thai%20research%20reactor%20%28TRR-1%2FM1%29" title=" Thai research reactor (TRR-1/M1)"> Thai research reactor (TRR-1/M1)</a>, <a href="https://publications.waset.org/abstracts/search?q=radiation%20shielding" title=" radiation shielding"> radiation shielding</a> </p> <a href="https://publications.waset.org/abstracts/41895/the-mcnp-simulation-of-prompt-gamma-ray-neutron-activation-analysis-at-trr-1m1" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41895.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">383</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1</span> Fusion Neutron Generator Dosimetry and Applications for Medical, Security, and Industry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kaouther%20Bergaui">Kaouther Bergaui</a>, <a href="https://publications.waset.org/abstracts/search?q=Nafaa%20Reguigui"> Nafaa Reguigui</a>, <a href="https://publications.waset.org/abstracts/search?q=Charles%20Gary"> Charles Gary</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Characterization and the applications of deuterium-deuterium (DD) neutron generator developed by Adelphie technology and acquired by the National Centre of Nuclear Science and Technology (NCNST) were presented in this work. We study the performance of the neutron generator in terms of neutron yield, production efficiency, and the ionic current as a function of the acceleration voltage at various RF powers. We provide the design and optimization of the PGNAA chamber and thus give insight into the capabilities of the planned PGNAA facility. Additional non-destructive techniques were studied employing the DD neutron generator, such as PGNAA and neutron radiography: The PGNAA is used for determining the concentration of 10B in Si and SiO2 matrices by using a germanium detector HPGe and the results obtained are compared with PGNAA system using a Sodium Iodide detector (NaI (Tl)); Neutron radiography facility was tested and simulated, using a camera device CCD and simulated by the Monte Carlo code; and the explosive detection system (EDS) also simulated using the Monte Carlo code. The study allows us to show that the new models of DD neutron generators are feasible and that superior-quality neutron beams could be produced and used for various applications. The feasibility of Boron neutron capture therapy (BNCT) for cancer treatment using a neutron generator was assessed by optimizing Beam Shaping Assembly (BSA) on a phantom using Monte-Carlo (MCNP6) simulations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=neutron%20generator%20deuterium-deuterium" title="neutron generator
