1. Digitised charged-particle discrimination in CsI detector signals
Kandidat-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionenSammanfattning : 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. LÄS MER
2. Identification of Neutrons Using Digitized Waveforms
Master-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionenSammanfattning : 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. LÄS MER
3. Development of a Detector System for Detection of Thermal Neutrons from Spent Nuclear Fuel
Master-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionenSammanfattning : 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. LÄS MER
4. Characterisation of a New Type of Solid Organic Scintillator for neutron-gamma Discrimination using Pulse-Shape DiscriminationTechniques
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/KärnfysikSammanfattning : 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. LÄS MER
5. Study of the pulse shape as a means to identify neutrons and gammas in a NE213 detector
Uppsats för yrkesexamina på avancerad nivå, Institutionen för neutronforskningSammanfattning : 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. LÄS MER
