  1. 1. Prospects for a Free Electron Laser at the FemtoMAX Beamline

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Johan Holmberg; [2024]
    Keywords : Free Electron Lasers; FEL; synchrotron radiation; MAX IV; FemtoMAX; GENESIS 1.3; XFEL; X-rays; soft X-rays; Physics and Astronomy;

    Abstract : A Free Electron Laser (FEL), is a device that generates extremely coherent and brilliant radiation using electrons accelerated to relativistic velocities in a particle accelerator. The process utilises similar equipment to what is used at a synchrotron source like MAX IV, but in addition there is an interaction between the relativistic electron beam and the generated radiation to achieve an exponential growth in radiation intensity.

  3. 2. Quantum Optical Description of High-order Harmonic Generation

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Isabel Moreno; [2024]
    Keywords : Physics and Astronomy;

    Abstract : High-order Harmonic Generation (HHG) is a highly non-linear process in which an atom interacts with a strong laser field. The laser field lowers the atomic potential barrier allowing bound electrons to escape into the continuum through tunnel ionization, propagate, and, with some probability, recombine with the parent ion.

  4. 3. The effect of recycling and processing routes on recrystallization in a secondary 3xxx aluminium alloy

    University essay from Jönköping University/JTH, Material och tillverkning

    Author : Anton Rolseth; [2023]
    Keywords : Aluminium alloys; sheet metal forming; grain boundary segregation; recrystallization; Zener pinning; casting; rolling;

    Abstract : Aluminium alloys have the possibility to be infinitely recycled. By only generating 5% of the emissions compared to primary aluminium, great CO2 savings can be made. One of the issues in manufacturing components entirely from post-consumer scrap is the presence of trace elements and impurities. Such elements can be Fe, Cu, Cr, P and Pb. READ MORE

  5. 4. Feasibility Study on Additive Manufacturing of Copper Windings using Electron Beam Melting

    University essay from KTH/Produktionsutveckling

    Author : Marilena Wiele; Murad Abulawi; [2023]
    Keywords : Electron beam melting; Additive manufacturing; Electric motor windings; Hairpin windings; Winding design; Copper; Parameter optimization; Electrical conductivity; Elektronstrålesmältning; Additiv tillverkning; Elmotorlindningar; Hårnålslindningar; Lindningsdesign; Koppar; Parameteroptimering; Elektrisk ledningsförmåga;

    Abstract : Within the framework of this thesis, the electron beam melting of pure copper for the purpose of producing electrical windings was examined. The conventional manufacturing process of copper windings was investigated, and the potential advantages offered by the design freedom inherent in the electron beam melting process were explored.

  6. 5. Vacuum Chamber Adaptation for Low-Power Electric Propulsion Testing : Optimizing Anode Configuration and Electrical Interface for Hollow Cathode Testing, and Conceptualizing a Setup for Field Emission Electric Propulsion Testing

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

    Author : Therese Bäckström; [2023]
    Keywords : Electric Propulsion; Field Emission Electric Propulsion Testing; FEEP Testing; Thruster Testing; Heaterless Hollow Cathode Testing; HHCTesting; Cathode Testing; Anode Design; Anode Configuration; Electrical Interface; Elektrisk Framdrivning; Fältjonisationsframdrivningstestning; Framdrivningstestning; Värmelös Hålkatodstestning; Katodtestning; Anoddesign; Anodkonfiguration; Elektriskt Gränssnitt;

    Abstract : Electric Propulsion (EP) is widely acknowledged as a crucial technology for future space missions, offering significant propellant savings and enabling exploration of planetary missions with smaller spacecraft (s/c). For precise attitude control of these smaller spacecraft, Field Emission Electric Propulsion (FEEP) has emerged as a favorable option due to its exceptional thrust controllability. READ MORE
