1. 1. Digitised charged-particle discrimination in CsI detector signals

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

   Author : Mats Bror Linus Persson; [2022]
   Keywords : Microball; Gammasphere; pulse-shape discrimination; scintillator; charge-comparison method; cosine similarity; exotic nuclei; fusion-evaporation reaction; Argonne National Laboratory; Physics and Astronomy;

   Abstract : This work is aimed at improving the discrimination of protons and α particles in digitised signals from CsI(Tl) scintillators. This has been achieved using pulse-shape discrimination, wherein the shape of the pulses is used to learn which particle is detected. READ MORE

   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

5. 4. 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

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
