6. Using forest reflectance modelling to estimate albedo for narrow-view satellites
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap; Lunds universitet/Fysiska institutionenSammanfattning : Surface albedo estimations from remote sensing are invaluable for energy balance descrip- tions in climate research. The aim of this work is to evaluate the possibility of using Sentinel-2 satellite data to get the total albedo of a small, vegetated area. LÄS MER
7. 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-laboratorietSammanfattning : 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
8. Investigation of plasma cleaning on molybdenum crystals for diagnostic mirrors in fusion devices
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : In the long-term energy scenario, nuclear fusion is a promising low-carbon and sustainable energy source. The unavoidable exposure of the wall materials to the plasma is a big challenge in realizing a fusion reactor. The plasma-facing components (PFCs) in the reactor wall will experience erosion deposition in the surface materials. LÄS MER
9. Improving polarizing neutron optics by introducing 11B4C as interlayers
Master-uppsats, Linköpings universitet/TunnfilmsfysikSammanfattning : In this report, the effects of adding 11B4C as interlayers into Fe/Si multilayers is studied. Fe/Si multilayers are commonly used for neutron polarization at large research facilities, and improving the polarizing properties would improve their efficiency. LÄS MER
10. Preparation and Characterization of Tb-Co Magnetic Films
L2-uppsats, Uppsala universitet/MaterialfysikSammanfattning : Thin films of terbium-cobalt alloy have been deposited by magnetron sputtering. They exhibit an out-of-plane magnetic anisotropy that may result in elongated domains. The effect of thicknesses and compositions on the domain structure has been studied systematically. LÄS MER
