  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. Development of a Detector System for Detection of Thermal Neutrons from Spent Nuclear Fuel

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

    Author : Daniel Söderström; [2016]
    Keywords : neutron detection; neutron; 10B; boron-10; nuclear physics; boron; neutron detector; scintillator; boron carbide; B4C; nuclear fuel; repository; SKB; Physics and Astronomy; Technology and Engineering;

    Abstract : The nuclear reaction 10B(n,alpha)7Li* was utilised to develop a neutron detection system. This system has the purpose of being used to detect the thermal neutron radiation emitted by spent nuclear fuel, before it is transported to a final repository. READ MORE

  3. 3. Characterisation of a New Type of Solid Organic Scintillator for neutron-gamma Discrimination using Pulse-Shape DiscriminationTechniques

    University essay from Uppsala universitet/Kärnfysik

    Author : Qadir Nishada; [2014]
    Keywords : EJ-299-33; PSD; Pulse-shape discrimination; plastic scintillator; neutron-gamma discrimination; scintillator decay times;

    Abstract : In this report the neutron-gamma discrimination capabilities of the new type of solid organic scintillator, EJ-299-33, was investigated using several pulse-shape discrimination (PSD) techniques. Among others, the analog zero-crossing method andthe digital charge-comparison and integrated-rise-time method were tested. READ MORE

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

    University essay from Uppsala universitet/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
