  1. 1. 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

  3. 2. 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.

  4. 3. Analys av platinaytor och platinatennytor under katalytisk etanoloxidation med röntgenfotoelektronspectroskopi

    Magister-uppsats, Malmö universitet/Institutionen för materialvetenskap och tillämpad matematik (MTM)

    Författare :Mats Viktor Löfstrand; [2023]
    Nyckelord :Pt3Sn; APXPS; Ethanol oxidation; Pt 111 ; Pt 223 ;

    Sammanfattning : Fuel cells are more efficient and cleaner than combustion engines. Ethanol as a fuel has a high energy density and is safer and easier to handle than hydrogen which is normally used in fuel cells. If efficient fuel cells on alcohol were available, they could be used for engines and power sources for electronics. LÄS MER

  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. Feasibility Study of X-ray Free Electron Lasers in Fourth Generation Storage Rings

    Kandidat-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen; Lunds universitet/MAX IV-laboratoriet

    Författare :Jordis Hansen; [2023]
    Nyckelord :XFEL; Storage Ring; Synchrotron Radiation; Physics and Astronomy;

    Sammanfattning : 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. LÄS MER
