1. 11. 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. 12. Can blue mussel shells be used for retrospective 14C-analysis in the marine environment of nuclear power plants?

   Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

   Författare :Sofia Bjarheim; [2024]
   Nyckelord :Radionuclide; Marine Environment; Blue Mussels; 14C; Nuclear Power Plant; Physics and Astronomy;

   Sammanfattning : Carbon-14 (14C) is one of the most important contributors to the collective effective dose of the public due to radioactive releases from nuclear power plants. However, the discharge of 14C from nuclear power plants (NPPs) into water has not been measured previously. LÄS MER

4. 13. Flow of charged particles in Pb-Pb and pp collisions at the LHC

   Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

   Författare :Mohamed Berkat; [2024]
   Nyckelord :Quark Gluon Plasma; QGP; Quantum Chromodynamic; QCD; flow coefficients; Event Plane; Cumulants; ALICE; Physics and Astronomy;

   Sammanfattning : This thesis investigates the transition of Quantum Chromodynamic (QCD) matter to a strongly interacting Quark Gluon Plasma (QGP), where quarks and gluons become deconfined. The expansion of this plasma exhibits characteristics of an ideal relativistic hydrodynamics system, suggesting a behavior similar to that of a perfect fluid. LÄS MER

5. 14. The active phase of Pt(110) during catalytic CO oxidation

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

   Författare :Hira Qazilbash; [2024]
   Nyckelord :Physics and Astronomy;

   Sammanfattning : CO oxidation is an important topic in heterogeneous catalysis, due to its role in industrial processes such as pollution reduction in the auto industry, and ethanol or other fuel production. In the automotive catalytic converters CO oxidation reduces the poisonous CO to CO2 by reacting with O2. LÄS MER

7. 15. Quantum Optical Description of High-order Harmonic Generation

   Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

   Författare :Isabel Moreno; [2024]
   Nyckelord :Physics and Astronomy;

   Sammanfattning : High-order Harmonic Generation (HHG) is a highly non-linear process in which an atom interacts with a strong laser field. The laser field lowers the atomic potential barrier allowing bound electrons to escape into the continuum through tunnel ionization, propagate, and, with some probability, recombine with the parent ion.
