1. 1. Prototyping of an automated cyclic Neutron Activation Analysis setup

   Master-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

   Författare :Cornelius Maurer; [2022]
   Nyckelord :Nuclear Physics; Neutron activation analysis; cyclic-NAA; Physics and Astronomy;

   Sammanfattning : A prototype Neutron Activation Analysis (NAA) setup based on a Deuterium-Tritium (DT) neutron generator is under development at Lund University. It serves as proof-of-principle for NAA based on a Compact Accelerator-driven Neutron Source. LÄS MER

3. 2. Development of a Neutron Activation Analysis station at the Lund Ion Beam Analysis Facility

   Kandidat-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

   Författare :Josephine Lindsey-Clark; [2021]
   Nyckelord :Neutron Activation Analysis; NAA; European Spallation Source; ESS; Lund Ion Beam Analysis Facility; LIBAF; Gamma-Ray Spectra; Physics and Astronomy;

   Sammanfattning : This report outlines the first stages of the development of the Neutron Activation Analysis station at the Lund Ion Beam Analysis Facility in the Division of Nuclear Physics, Lund University. The motivation for this project is to use the Neutron Activation Analysis detection technique for environmental monitoring around the European Spallation Source, soon to come into operation. LÄS MER

4. 3. Benchmarking fission rate simulations through comparison with neutron activation data

   L3-uppsats, Uppsala universitet/Tillämpad kärnfysik

   Författare :Karlsson Peter; [2020]
   Nyckelord :Neutron activation; Gamma spectroscopy; Fission;

   Sammanfattning : Metal foils were implemented in a measurement of neutron-induced fission at the IGISOL facility in 2016. These foils were activated by a neutron flux during the experiment and measured after the beam was turned off. The radioactive products from the neutron activation were identified in an analysis of γ-ray spectroscopy data. LÄS MER

5. 4. Characterisation of a neutron experimental station at the Lund Ion Beam Analysis Facility

   Master-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

   Författare :Markus Kristensson; [2018]
   Nyckelord :neutrons; fast neutrons; thermal neutrons; neutron production; fusion; target materials; moderators; moderator materials; beam dump materials; neutron detection; neutron detector; coincidence measurements; nuclear physics; LIBAF; Lund Ion Beam Analysis Facility; particle accelerator; Physics and Astronomy;

   Sammanfattning : At the 3 MeV light ion accelerator of the Lund Ion Beam Analysis Facility (LIBAF), a beamline is about to be constructed with the purpose of producing neutrons as a higher yield complement to the current Source-Testing Facility. When operational, the beamline will provide the possibility of tagging both thermal and fast neutrons. LÄS MER

7. 5. Trace element analysis based on neutron activation with coincident gamma ray detection

   Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Kärnfysik

   Författare :Jessica Delgado; [2017]
   Nyckelord :scintillator detectors; gamma ray; gamma radiation; spectrometer; neutron activation analysis; trace element; Physics and Astronomy;

   Sammanfattning : In this work, six soil samples have been analyzed. The samples come from different sedimentary layers on Earth. They were previously studied with the objective to find the trace concentration of iridium, to correlate the increased concentrations of iridium with meteorite impacts that have occurred on Earth.
