1. 21. Simulations of stray radiation in the European XFEL undulators with the Geant4 toolkit

   University essay from Stockholms universitet/Fysikum

   Author : Guillermo Lopez Basurco; [2022]
   Keywords : Geant4; Monte Carlo simulations; XFEL undulators; gamma radiation flux;

   Abstract : The European XFEL is an X-ray free electron laser research facility that generates ultrashort, high intensity flashes. Three SASE undulator systems are made of undulator segments and intersection components. READ MORE

3. 22. CFD Simulations of Velocity and Temperature Distributions of the AuraGen Axial Flux Machine

   University essay from KTH/Maskinkonstruktion (Inst.)

   Author : Huanyu Chen; [2022]
   Keywords : CFD simulation; Induction machine; Temperature distribution; Velocity distribution; CFD-simulering; Hastighetsfördelning; Induktionsmaskin; Temperaturfördelning;

   Abstract : Axial flux induction machines are attractive solutions for electric vehicle applications nowadays. Thanks to their high torque density and no need for rare-earth material for permanent magnets, axial flux induction machines are the most used electric machine type with good performance and low prices.

4. 23. First Principles Studies Of 2D Magnets

   University essay from

   Author : Yahya Fayazi; Linus Jacobsson; Folke Gustafsson; [2022]
   Keywords : 2D material; ab initio; magnet; Quantum Espresso; Density Functional Theory; DFT; CrCl3; CrBr3; CrI3; 2D material; 2 dimensionella material; två dimensionella material;

   Abstract : The aim of this project is to examine the electric and magneticproperties of three monolayer chromium trihalides when doped withdifferent transitions metals, that is CrXY_6, where X=(Mn,Fe,Co,Ni,V)and Y=(Cl,Br,I). The calculations were made using the software programQuantum Espresso that used density functional theory to solveSchrödinger’s equation. READ MORE

5. 24. Material Supply Risks for the Energy Transition: A Quantitative Analysis of Resources, Production Concentration and Geopolitical Risks

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Ria Pozybill; [2022]
   Keywords : Sustainable development; Critical minerals; Geopolitical risks; Cobalt; Rare earths; Lithium;

   Abstract : The Paris Agreement aims to limit the global temperature to below 2°C above the pre-industrial level. In order to achieve this target, almost 200 countries committed to Nationally Determined Contributions to reduce their greenhouse gas emissions. Diverse strategies are applied to achieve the necessary emissions reductions. READ MORE

6. 25. Magnetically tunable microwave resonator/filter

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Zhi Ye; [2022]
   Keywords : Magnetic tuning; Ferrite; Substrate integrated waveguide resonator; Substrate integrated waveguide filter; Magnetisk inställning; Ferrit; Substratintegrerad vågledarresonator; Substratintegrerad vågledarfilter;

   Abstract : The magnetic tunability of ferrites has been studied and applied on many electric components for working in various frequency bands. Filters or resonators loaded by ferrites can thus work for different frequency requirements by tunning external biasing field. However, filters or resonators built by traditional waveguides are large in size. READ MORE
