  1. 1. Constructing and commissioning of a Multi-Grid neutron detector prototype for the European Spallation Source

    University essay from Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen; Lunds universitet/European Spallation Source ESS AB

    Author : Rebecka Wahlén; [2022]
    Keywords : Physics and Astronomy;

    Abstract : A prototype of a novel 10B-based neutron detector called the Multi-Grid detector has been constructed, tested and commissioned for the European Spallation Source (ESS). The detector is constructed after the specifications set by the CSPEC instrument at ESS and is therefore called the CSPEC Multi-Grid detector. READ MORE

  3. 2. 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

  4. 3. 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

  5. 4. 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

  6. 5. 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
