11. RF Compressor (SLED) Phase-Modulation to Reduce Peak Fields in the MAX IV Linear Accelerator
Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknikSammanfattning : Modern particle accelerators need strong electric fields in order to produce high energy particles. Such high voltages are typically reached by injecting pulsed radio frequency power through several steps of amplification. At the end, pulse compression is used to further improve the energy gain at the cost of pulse-length. LÄS MER
12. Learning the shapes of protein pockets
Master-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknikSammanfattning : The comparison of protein pockets plays an important role in drug discovery. Through the identification of binding sites with similar structures, we can assist in finding hits and characterizing the function of proteins. Traditionally, the geometry of cavities has been described with scalar features, which are not fully representative of the shape. LÄS MER
13. Mapping edge vegetation in connection to beech forest to locate potential habitats for red-listed beetles in Scania, Sweden
Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : The number of species classified as red-listed has increased by 11% between 2015 and 2020, with beetles and butterflies being especially affected. Among these are the vulnerable longhorned beetle (Stictoleptura scutellata) and the endangered false blister beetle (Ischnomera sanguinicollis). LÄS MER
14. Particle Simulation and Optimization of a Relativistic Magnetron for HPM Applications
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Fasta tillståndets elektronikSammanfattning : A relativistic magnetron (RM) is a high-power microwave (HPM) source. The main objective of the RM is to generate directed electromagnetic pulses with high power, which can be used in e.g. HPM weapons and for electromagnetic compatibility testing. LÄS MER
15. Feasibility Study of Resistivity Measurement of Metal Surfaces to Address Potential Dislocations Caused by Surface Conditioning
Master-uppsats, Uppsala universitet/FREIASammanfattning : High electrical fields are needed inside the accelerating cavities of particle accelerators in order to accelerate the particles to higher energies in shorter distances. But high electrical fields will lead to electrical breakdowns. LÄS MER
