1. Constructing and Commissioning HELIOS – A High Harmonic Generation Source for Pump-Probe Measurements with sub 50 fs Temporal Resolution : The Development of Experimental Equipment for Extreme Ultraviolet Spectroscopy
Abstract : This thesis presents HELIOS, an in-house laboratory for time-resolved pump-probe spectroscopy with extreme-ultraviolet (XUV) probe radiation. A wide span of pump wavelengths can be generated using commercial laser equipment while XUV probe radiation is generated via a high harmonic generation process in a noble gas delivering probe photons with energies between 20 eV and 72 eV.

2. The evolution of TOFu : Developing and utilizing neutron time-of-flight spectrometry of deuterium and tritium fusion plasmas at JET
Abstract : Considerable effort has been invested in attempting to generate electricity from the energy released in controlled thermonuclear fusion reactions, with a European fusion research roadmap stretching beyond 2050. Our current endeavors may culminate in a virtually inexhaustible, low-carbon energy source for future generations. READ MORE

3. Appearance and photographs of people in flight : A qualitative study of photojournalistic practices in spaces of (forced) migration
Abstract : This study explores photojournalistic practices by investigating how spaces of (forced) migration, as well as the people and objects moving in and across them, appeared in Swedish newspapers in 2015.Photographs are unique objects of study, as the presence of people in certain spaces becomes directly observable through them.

5. Detector Considerations for Time-of-Flight in Positron Emission Tomography
Abstract : Positron-Emission-Tomography (PET) is a modern imaging technique in nuclear medicine providing quantitative 3D distribution of a radioactive tracer substance in the human body. The gamma-detector is the first link in the chain of components that constitutes a PET. READ MORE
