1. Energy reconstruction with artificial neural networks on LDMX simulations
Kandidat-uppsats, Lunds universitet/Partikelfysik; Lunds universitet/Fysiska institutionenSammanfattning : It is clear from evidence such as rotational curves and cosmic microwave background measurements that dark matter exists. The light dark matter experiment (LDMX) will search for dark matter in the sub-GeV range. It will do this using missing-momentum measurements of electrons interacting with a Tungsten target. LÄS MER
2. Nanoscale detection of insulin granule sub-structures using dSTORM imaging
Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionenSammanfattning : Diabetes mellitus is a global disease, mainly caused by insufficient insulin secre- tion from pancreatic islet β-cells. Insulin is stored in the granules of islet β-cells and released in response to extracellular stimuli e.g. glucose. LÄS MER
3. Test setup for LDMX HCal readout
Kandidat-uppsats, Lunds universitet/Partikelfysik; Lunds universitet/Fysiska institutionenSammanfattning : It is evident from cosmological observations such as the Cosmic Microwave Background, and the motion of galaxies, that the universe consists of approximately 5 times more mass than visible matter can account for. The Light Dark Matter eXperiment (LDMX) will take a unique approach in its hunt for dark matter; it will look for missing momentum signals in electron collisions with a Tungsten target, and will be looking in the sub GeV energy range for evidence of dark matter interactions.

4. Searching for Dark Photons with Jet
Kandidat-uppsats, Lunds universitet/Teoretisk partikelfysikSammanfattning : Dark matter is the greatest mystery of modern particle physics and cosmology. Although an overwhelming amount of observational cosmological evidence has pointed towards a dark sector, only its gravitational effect has been experimentally confirmed. LÄS MER
5. Characterization of InAs-Al semiconductor-superconductor hybrid devices
Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionenSammanfattning : In this thesis we study charge and spin transport through InAs-Al nanowire superconductor-semiconductor hybrid devices. We focus on assessing the quality of the InAs-Al contact interface when using a weak HCl acid to wet-etch the nanowire surface prior to metal evaporation. LÄS MER
