1. Simulation-based discrimination of Crab pulsar models with XL-Calibur
University essay from KTH/FysikAbstract : Polarisation of X-ray light is being investigated with polarimeters to extend the borders of what can be observed. Distant compact objects, such as pulsars, that are to small on the sky to be analysed with imaging can be investigated by analysing the polarisation of the emitted light. This can reveal physics previously hidden by their small nature. READ MORE

2. Structural analysis of HZO thin film and electrode using X-ray diffraction
University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionenAbstract : Since its discovery in 2011, the ferroelectricity of thin films based on HfO2 has been studied intensively. In particular, thin films with a 1:1 ratio of HfO2 and ZrO2 (HZO) has been of great interest. The ferroelectricity arises from a non-centrosymmetric orthorhombic (o) phase of HZO whose prevalence is dependent on the processing conditions. READ MORE

3. Prospects for a Free Electron Laser at the FemtoMAX Beamline
University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionenAbstract : 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.

4. Development of Advanced X-ray Micro-Tomography Helical Scan andTomographic Data Processing
University essay from Högskolan i Gävle/Avdelningen för elektroteknik, matematik och naturvetenskapAbstract : Micro-computed tomography (Micro-CT) is an imaging technique that allows for high-resolution,three-dimensional (3D) internal visualization of small objects in a non-destructive manner. However,a significant limitation arises when attempting to image elongated samples at higher resolutions andmagnifications due to the inherently small field of view (FOV). READ MORE

5. Feasibility Study of X-ray Free Electron Lasers in Fourth Generation Storage Rings
University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen; Lunds universitet/MAX IV-laboratorietAbstract : This thesis studies the feasibility of a cavity based X-ray free electron laser in a fourth generation storage ring. The cavity design allows for modulation of the electron beam over several passes through the undulator. Simulations based on the PETRA IV facility are done to create the photon flux spectrum of a light pulse produced by an undulator. READ MORE
