1. Fitting a photospheric prompt emission model to GRB data: The Kompaneets RMS approximation (KRA)
Master-uppsats, KTH/FysikSammanfattning : Gamma-ray bursts (GRBs) are some of the most energetic events in the universe. Shocks occurring below the photosphere are likely radiation mediated shocks (RMSs) and are suspected to shape the spectra. Due to computational costs of simulating RMSs, models had not been fitted to data and a faster model was needed. LÄS MER
2. Development of Radon Detectors for Earthquake Prediction
Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)Sammanfattning : The purpose of this project is to simulate the detection of γ-ray spectra emitted by radon isotopes and their daughters. This is done as a contribution to the development of radiation detectors to be used in a research project investigating the possibility of using increased amounts of the radioactive gas radon as an earthquake precursor.

3. Prompt emission in Gamma-ray bursts; Photospheric Radiation from Synchrotron-Like spectra
Kandidat-uppsats, KTH/FysikSammanfattning : Gamma-ray bursts (GRBs) are the most luminous phenomena in the Universe, explosions whoseenergy is generated by supernovae or mergers of dense objects such as neutron stars. The GRBemission is divided into the prompt emission phase characterized by γ-ray radiation and the afterglowof lower energy radiation. LÄS MER
4. Characterization of a Bismuth germanate Anti-Compton Scattering Shield for use with a Germanium COMPEX detector module
Kandidat-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionenSammanfattning : The scope of this work is to help determine the functional improvement brought on by introducing a Bismuth germanate (BGO) Anti-Compton Scattering (ACS) shield system to a germanium COMPEX detector module. The COMPEX germanium detector module is already an extremely useful addition in examining gamma-ray spectroscopy. LÄS MER
5. Development of a Neutron Activation Analysis station at the Lund Ion Beam Analysis Facility
Kandidat-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionenSammanfattning : This report outlines the first stages of the development of the Neutron Activation Analysis station at the Lund Ion Beam Analysis Facility in the Division of Nuclear Physics, Lund University. The motivation for this project is to use the Neutron Activation Analysis detection technique for environmental monitoring around the European Spallation Source, soon to come into operation. LÄS MER
