3. 22. Study and characterization of energetic particles from the solar wind entering the magnetosheath region

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Farid Hedayati; [2022]
   Nyckelord :Magnetospheric Multiscale Mission MMS ; Magnetosheath classification; Particles; Time series analysis; Space plasma physics;

   Sammanfattning : The emphasis of the thesis is on understanding how the high-energy particles of the foreshock are transmitted into the magnetosheath and how this process can be used to specify the conditions upstream of the bow shock with the help of local magnetosheath measurements. In this study, through analyzing the data from the MMS satellites, I try to draw a connection between the flux and wind direction related to Earth’s bow shock. LÄS MER

4. 23. Modeling of Low-Energy Neutron Scattering in Liquid Hydrogen Using NCrystal

   Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/European Spallation Source ESS AB; Lunds universitet/Kärnfysik

   Författare :Tim Günter; [2022]
   Nyckelord :ESS; European Spallation Source; neutron; scattering; moderator; liquid hydrogen; modeling; ncrystal; njoy; Physics and Astronomy;

   Sammanfattning : The European Spallation Source ESS, under construction in Lund, Sweden, aims to produce high-brightness and intensity neutrons for a multitude of experiments upon completion. An efficient production of neutrons requires elaborate understanding of the moderation process which slows the neutrons from relativistic speed to a kinetic energy of meV. LÄS MER

5. 24. Thermoelectric measurements on InAs nanowires with a ratchet-barrier

   Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Fasta tillståndets fysik

   Författare :Hanna Lundström; [2022]
   Nyckelord :Physics and Astronomy;

   Sammanfattning : Efficient extraction of thermal energy from electrons at the micro- and nanoscale is a long-standing scientific goal that could enable novel types of heat engines, heat management, and solar cell applications. Semiconductor nanowires are a promising system for investigating such devices for several reasons, such as their thermoelectric properties, and the potential to be grown in heterostructures with high flexibility.

7. 25. Thermal Initiation of Energetic Materials Caused by Hot Fragments

   Master-uppsats, KTH/Matematik (Avd.)

   Författare :Sirak Ghebreamlak; [2022]
   Nyckelord :Applied mathematics; computational mathematics; heat equation; thermal initiation; chemical kinetics; energetic materials; Tillämpad matematik; beräkningsteknik; värmeledningsekvationen; termisk initiering; kinetik; energetiska material;

   Sammanfattning : The cause of unintentional initiations of energetic materials is an important area of study due to the risks that comes with storing energetic materials such as high explosives. The current models used to simulate the process of heating energetic materials by a hot metal fragment do not give reliable predictions. LÄS MER
