  1. 1. 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.

  3. 2. 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

  4. 3. (1,3-di-tert-butyltriazenide) Cu(I) as vapor deposition precursor

    Kandidat-uppsats, Linköpings universitet/Kemi

    Författare :Peggy Bagherzadeh; [2023]
    Nyckelord :Vapor deposition; CVD; ALD; triazenide;

    Sammanfattning : In the past few decades, devices such as computers have become smaller, and their performance has improved beyond comparison. Semiconductors and interconnectors are used in almost all devices today and are made of thin films. LÄS MER

  5. 4. Interfacial Dynamics at Surface Modified Molecular/Perovskite Solar Cells : How measurements are made to understand solar cell stability

    Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Benjamin Verbeek; [2023]
    Nyckelord :perovskite; solar cell; solar; energy; XPS; synchrotron;

    Sammanfattning : Humanity has great energy demands, and must simultaneously combat climate change by curbing anthropogenic greenhouse gas emissions. Perovskite solar cells (PSC) provide a low-carbon energy source, at lower production costs than traditional silicon-based solar cells. PSC's suffer some issues with long-term stability. LÄS MER

  7. 5. Aluminum levels in the O-horizon of soils near Sundsvall, Sweden : Are levels of Al elevated due to smelter emission?

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Mattias Sundin; [2023]
    Nyckelord :Aluminium; Smelter emissions; O-horizon; Al concentration; Scots’ pine needles;

    Sammanfattning : Aluminum (Al) is a potentially toxic element for humans, animals, and plants. Al emitted from smelter plants is one source of Al that may be responsible for increased exposure to humans and the environment. LÄS MER
