  1. 1. A Machine Learning Approach on Analysis of Emission Spectra for Application in XFEL Experiments

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Harald Agelii; [2023]
    Keywords : Structural biology; Machine learning; Neural networks; emission spectrum; XFEL; X-ray free electron laser; SFX; Serial femtosecond X-ray crystallography; Proteins; Diagnostics;

    Abstract : In this thesis we investigate two potential applications of machine learning in the context of X-ray imaging and spectroscopy of biological samples, particularly such using X-ray free electron lasers (XFEL). We first investigate the possibility of using an emission spectrum, recorded from a sample after being probed by an incident X-ray, as a diagnostic tool. READ MORE

  3. 2. Optimization of alloys recovery in steel scrap sorting : Technological, economic and environmental considerations for a better chromium, nickel and molybdenum recovery in steel scrap

    University essay from KTH/Materialvetenskap

    Author : Simone Quintè; [2023]
    Keywords : Steel scrap sorting; stainless steel; Chromium; Nickel; Molybdenum; alloys recovery; Laser Induced Breakdown Spectroscopy; revenue modeling; CO2 emissions modeling; Stålskrot Sortering; rostfritt stål; Krom; Nickel; Molybden; återvinning av legeringar; Laserinducerad nedbrytningsspektroskopi; intäktsmodellering; Modellering av CO2-utsläpp;

    Abstract : Today’s steelmaking industry is highly dependent on steel scrap supply. In order to reduce the greenhouse gas emissions (GHGs) deriving from the steel industry, it is of utmost importance to ensure that high percentages of steel scrap are recycled, reducing the reliance on the traditional ore-based steelmaking, which is significantly more environmentally impactful.

  4. 3. Adaptation and Redesign of SPECTRAP Beamline

    University essay from

    Author : Oliver Kraft; Elina Hollsten; [2023]
    Keywords : ;

    Abstract : Replacement of the superconducting magnet used in the SPECTRAP laser spectroscopy experiment at GSI necessitates redesign of some associated components. This thesis investigates a potential new beamline for SPECTRAP using a single pulse drift tube to slow the ions down. READ MORE

  5. 4. Numerical simulations of ultrafast dynamics in plasmonic nanostructures

    University essay from Umeå universitet/Institutionen för fysik

    Author : Nils Henriksson; [2023]
    Keywords : Ultrafast nanophotonics; Three temperature model; Numerical simulations;

    Abstract : Plasmonic effects in nanosized particles enhance the interaction between light and matter due to the localized surface plasmon resonance, with potential applications such as all-optical transistors and optical computers. Commonly, the dynamics of nanoparticles’ optical properties are assessed via pump-probe spectroscopy, where a plasmonic structure is exited by an initial laser, the pump. READ MORE

  6. 5. Development of MOKE spectrometer

    University essay from Uppsala universitet/Materialfysik

    Author : Sebastian Åberg; [2023]
    Keywords : MOKE; Spectroscopy;

    Abstract : The magneto-optical Kerr effect (MOKE) describes the change in polarization of light reflected from a magnetic surface. This change is proportional to the magnetization and depends on the wavelength of light. Because of these properties, MOKE has found use as a tool to probe magnetism in matter. READ MORE
