  1. 1. Identification of Neutrons Using Digitized Waveforms

    University essay from Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Rasmus Kjær Høier; [2019]
    Keywords : Digitizer; neutron; gamma-ray; pulse-shape discrimination; CNN; convolutional neural network; charge comparison; time of flight; source-testing facility; STF; Physics and Astronomy;

    Abstract : The advantages of performing neutron-tagging measurements using a waveform digitizer are explored. An existing analog setup consisting of modular crate electronics at the Source-Testing Facility at the Division of Nuclear Physics in Lund, Sweden has been digitally replicated. READ MORE

  2. 2. Vanadium-based neutron-beam monitor

    University essay from Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Vendula Maulerova; [2019]
    Keywords : thermal neutrons Helmholtz-Zentrum Berlin Neutron-beam monitor Vanadium; Physics and Astronomy;

    Abstract : A prototype invasive (quasi-parasitic) thermal-neutron beam monitor based on isotropic neutron scattering from a thin natural Vanadium foil and standard $^3$He proportional counters has been conceptualized, designed, simulated, calibrated, and commissioned. As the beam monitor is invasive, very low neutron-beam attenuation is a necessary characteristic. READ MORE

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

    University essay from Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Markus Kristensson; [2018]
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 4. Two-Dimensional Radiation Field Map of a Be-based Source

    University essay from Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Henrik Söderhielm; [2017]
    Keywords : Nuclear Physics Particle Detectors Neutrons Gamma Rays European Spallation Source Lund University; Physics and Astronomy;

    Abstract : The aim of this project was to measure the profile of the radiation exiting an aperture of the Aquarium at the Source Testing Facility at the Division of Nuclear Physics at Lund University. So far, the outgoing beam of radiation at the aperture of the Aquarium has been assumed to be uniform. READ MORE

  5. 5. The Radiological Footprint of a Be-based Neutron Source

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Kärnfysik

    Author : Sharareh Koufigar; [2015]
    Keywords : Physics and Astronomy;

    Abstract : The radiological footprint of a Be-based neutron source embedded within the Aquarium of the Source-Testing Facility (STF) at the Division of Nuclear Physics at Lund University will soon be carefully mapped. As a precursor to this measurement program, neutron and gamma-ray energy spectra at beamport apertures have been measured using 3He and LaBr3(Ce) (cerium-activated lanthanum bromide) detectors.
