1. Prospects for a Free Electron Laser at the FemtoMAX Beamline
Kandidat-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionenSammanfattning : A Free Electron Laser (FEL), is a device that generates extremely coherent and brilliant radiation using electrons accelerated to relativistic velocities in a particle accelerator. The process utilises similar equipment to what is used at a synchrotron source like MAX IV, but in addition there is an interaction between the relativistic electron beam and the generated radiation to achieve an exponential growth in radiation intensity.

2. Vibrational signals as indicators of soil fauna health? : A novel approach to environmental monitoring of ants
Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskapSammanfattning : Soil fauna provides processes of crucial importance for ecosystem functions, but our ability to observe their actions often depend on destructive methods where the integrity of the studied environment (the soil) is compromised. In this study, I develop and test a new generation of environmental monitoring tools that utilize vibrations made by soil macrofauna to inform about their performance and health. LÄS MER
3. Measuring Sprint Speed with Ultra-wideband Technology
Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Sprinting can be an important ability in sports, and there are many methods for measuring sprint performance. Two common methods are hand-held timing and fully automatic timing systems. However, hand-held timing is inaccurate due to reaction time, and fully automatic timing can be impractical since it involves complex equipment. LÄS MER
4. Adaptation and Redesign of SPECTRAP Beamline
Kandidat-uppsats,Sammanfattning : Replacement of the superconducting magnet used in the SPECTRAP laser spectroscopy experiment at GSI necessitates redesign of some associated components. This thesis investigates a potential new beamline for SPECTRAP using a single pulse drift tube to slow the ions down. LÄS MER
5. Discharge and Flame Chemistry in Lithium-Ion Battery Vent Gases : Investigations using Breakdown Experiments with Laser-Based Diagnostics
Master-uppsats, Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionenSammanfattning : Due to the environmental impact of fossil fuels, there has been a growing interest in lithium-ion batteries for electric vehicles. However, safety concerns have arisen regarding potential fire hazards associated with the vent gases of these batteries. LÄS MER
