1. 1. Simulation-based discrimination of Crab pulsar models with XL-Calibur

   Master-uppsats, KTH/Fysik

   Författare :Dennis Åkerström; [2024]
   Nyckelord :Astroparticle Physics; Astrophysics; Detector Physics; Simulation; Theoretical Physics; Engineering Physics; Pulsar models; Crab pulsar; Astropartikelfysik; Astropartikelfysik; Detektorfysik; Simulering; Teoretisk Fysik; Teknisk Fysik; Pulsar modeller; Krabbpulsaren;

   Sammanfattning : 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. LÄS MER

3. 2. Structural analysis of HZO thin film and electrode using X-ray diffraction

   Kandidat-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

   Författare :Elliot Winsnes; [2024]
   Nyckelord :HZO; hafnia; hafnium dioxide; zirconium dioxide; ferroelectricity; ferroelectric; synchrotron radiation; X-ray diffraction; Physics and Astronomy;

   Sammanfattning : 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. LÄS MER

4. 3. Prospects for a Free Electron Laser at the FemtoMAX Beamline

   Kandidat-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

   Författare :Johan Holmberg; [2024]
   Nyckelord :Free Electron Lasers; FEL; synchrotron radiation; MAX IV; FemtoMAX; GENESIS 1.3; XFEL; X-rays; soft X-rays; Physics and Astronomy;

   Sammanfattning : 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.

5. 4. Visualisering av signaler från delay line detektor

   Kandidat-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

   Författare :Abd Al Salam Abo Taha; Israa Ali; [2023]
   Nyckelord :Delay line detector; Python; Oscilloscope; Microchannel Plate; Artifacts; Trigger; Detector image; Anode; Synchrotron light; X-ray.; Technology and Engineering;

   Sammanfattning : MAX IV laboratoriet ger forskare möjlighet att analysera och studera material på atomnivå genom att använda högenergetiska ljusstrålar. Synkrotronljusanläggningen MAX IV genererar intensiva strålar av elektromagnetisk strålning, inklusive röntgenstrålning. LÄS MER

7. 5. Development of Advanced X-ray Micro-Tomography Helical Scan andTomographic Data Processing

   Master-uppsats, Högskolan i Gävle/Avdelningen för elektroteknik, matematik och naturvetenskap

   Författare :Yoseph Abraham; [2023]
   Nyckelord :;

   Sammanfattning : 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). LÄS MER
