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. Effects of Ultrafast Ionization in X-ray Coherent Diffraction Imaging
Master-uppsats, KTH/KemiSammanfattning : Koherent Diffraktionsavbildning med en intensiv röntgenpuls från en Frielektronlaser har möjliggjort strukturbestämning av isolerade nanopartiklar som inte går att studera med hjälp av konventionella metoder, så som elektronmikroskopi. En mycket kort pulslängd tillsammans med spridningssignalens beroende av objektets elektroniska struktur medför också möjligheten att studera inducerad ultrasnabb dynamik med denna teknik. LÄS MER
3. A Machine Learning Approach on Analysis of Emission Spectra for Application in XFEL Experiments
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för fysik och astronomiSammanfattning : In this thesis we investigate two potential applications of machine learning in the context of X-ray imaging and spectroscopy of biological samples, particularly such using X-ray free electron lasers (XFEL). We first investigate the possibility of using an emission spectrum, recorded from a sample after being probed by an incident X-ray, as a diagnostic tool. LÄS MER
4. Coordinate Mark Out Using Intersecting Line Lasers
Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : In the entertainment industry, where temporary structures are erected in a new venue every day, floor markings play an important role during the set up. Today, mark out is commonly done using tape measures - a very tedious and time consuming process. LÄS MER
5. Laser dazzling of CMOS imaging sensors using amplitude modulated and continuous wave lasers
Master-uppsats, Umeå universitet/Institutionen för fysikSammanfattning : Protecting sensitive information is important, especially in defence applications. As cameras become more common, developing countermeasure systems that limit the information gathering capabilities of imaging sensors would be beneficial. LÄS MER
