  1. 1. Nonlinear Optics Studies on the MAX IV Storage Rings

    Author : David K Olsson; Lunds universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; accelerator physics; synchrotron; storage ring; magnetic optics; non-linear optics; characterisation; optimisation;

    Abstract : The MAX IV Laboratory in Lund, Sweden, houses two electron storage rings operating at the energies 1.5, and 3 GeV. Both of these produce high-brilliance synchrotron radiation for beamline users. While the 1. READ MORE

  2. 2. The Formation and Breakdown of Passive Film on Ni Alloys : in situ synchrotron studies

    Author : Alfred Larsson; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Passivity; Corrosion; Degradation; Nickel alloys; synchrotron; in situ; Fysicumarkivet A:2023:Larsson;

    Abstract : Corrosion results in huge annual costs and a large environmental footprint. The corrosion rate of some alloys can be made negligible by the presence of a spontaneously forming oxide film on the surface, a so-called passive film. Famous examples of alloys exhibiting passivity are stainless steels. READ MORE

  3. 3. Optical Studies For Synchrotron Radiation Beamlines

    Author : Walan Grizolli; Lunds universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Synchrotron Radiation; Optics; X-ray Optics; Beamline; Polarimetry; Coherence; Storage Rings; Diffraction Limited Storage Rings;

    Abstract : Synchrotron radiation sources have greatly contributed to the progress in many fields of science. The development of the storage ring technologies has made possible to obtain very low emittance electron beams, which together with the use of undulators allow guiding a very high photon flux into a very small spot required by the experiments.

  4. 4. Efficiency Enhancement Techniques for Free-Electron Lasers

    Author : Alan Mak; Lunds universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; free-electron laser; accelerator physics; efficiency enhancement; undulator tapering; phase jump method; synchrotron radiation; Fysicumarkivet:2017:Mak;

    Abstract : The central question addressed in this thesis is how to make the free-electron laser (FEL) more efficient. In recent years, coherent diffraction imaging provides an important motivation for efficiency enhancement. This is because a more efficient FEL process enables converting a larger fraction of the electron beam's power into optical power. READ MORE

  5. 5. Accelerator physics studies of the MAX-lab storage rings

    Author : Magnus Sjöström; Lunds universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Electron accelerator; linear optics; storage ring; characterisation; synchrotron radiation; emittance; intrabeam scattering; electron beam profile;

    Abstract : Within research, synchrotron radiation is a highly useful probe for the study of materials, their properties and structures. Currently, no other radiation source allows the combination of high intensity and short wavelengths. READ MORE
