  1. 1. Characterization of neutron detection efficiency in a liquid organic scintillator

    University essay from

    Author : Ebba Wargh; Nadine Tabeshnia; [2023]
    Keywords : ;

    Abstract : Neutron detectors in the form of liquid organic scintillators are widely used for nuclear disarmament purposes. The main purpose of this thesis is to characterize the neutron detection efficiency of the organic liquid scintillator EJ-309 using Monte Carlo based simulations in the simulation program Geant4.

  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. Design, Construction and Characterization of a Portable Fast-Neutron Detector

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

    Author : Nicholai Mauritzsson; [2017]
    Keywords : fast-neutrons; detector; plastic scintillator; NE110; neutron tracking; scintillation; spallation; european spallation source; sonnig; Physics and Astronomy;

    Abstract : At European Spallation Source ERIC, 2 GeV proton bunches will be accelerated towards a tungsten target where spallation will occur, producing a wide neutron energy spectrum. Despite the shielding and moderators in place to stop and/or reduce their energy, a significant portion of the most energetic neutrons, called prompt neutrons, might still reach the sample position of a neutron-scattering instrument.

  5. 4. Fast Photoneutron Detection

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

    Author : Emil Rofors; [2016]
    Keywords : Neutron; neutron detection; spallation; scintillator; Monte Carlo; Physics and Astronomy;

    Abstract : The purpose of this project was to investigate fast photoneutron production from a series of materials commonly used for backing neutron beam guides. Fast neutrons were knocked out of these materials by exposing them to to high-energy photons at the Tagged-Photon Facility at MAX-lab in Lund, Sweden. READ MORE

  6. 5. Study of the pulse shape as a means to identify neutrons and gammas in a NE213 detector

    University essay from Institutionen för neutronforskning

    Author : Mikael Höök; [2006]
    Keywords : pulse shape discrimination; pulse shape analysis; neutron; liquid scintillator;

    Abstract : This report describes investigations of the NE213-detector and the possibility to utilize pulse shape analysis to separate neutrons and gammas in a mixed emission field. Neutron fluxes are often contaminated with gammas, to which the detectors are sensitive. READ MORE
