  1. 11. Fermi-LAT gamma-ray and multi-wavelength SED analysis and modelling of PKS 0426-380 : A thesis analysing the behaviour and properties of the blazar PKS 0426-380

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Författare :Nathanael Löfström; [2022]
    Nyckelord :active galactic nucleus; black hole; AGN; Fermi-LAT; JetSeT;

    Sammanfattning : An analysis is made on the Flat Spectrum Radio Quasar PKS 0426-380 using two sets of data. The first set of data is the Fermi-LAT data collected over the time 54682.66 − 59317.66 in Modified Julian Date within the energy range of 100 MeV to 500 GeV. LÄS MER

  3. 12. Multi-spectral X-ray imaging with a laser-plasma accelerator

    Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Författare :Andrea Angella; [2022]
    Nyckelord :Multi-spectral imaging; single-photon counting; X-ray absorption spectroscopy; XAS; LWFA; laser-wakefield acceleration; K-edge; imaging; metal-detection algorithm; Physics and Astronomy;

    Sammanfattning : This master thesis focuses on the creation of an algorithm to perform multispectral imaging of a metallic target using X-rays. The generation of an ultrashort high-power low-divergent X-ray beam is performed by means of a Ti:Sapphire laser driven wake-field plasma accelerator. LÄS MER

  4. 13. X-ray-induced intermolecular reactions in mixed clusters

    Kandidat-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Astrid Bergman; [2022]
    Nyckelord :molecular cluster; biophysics; X-ray;

    Sammanfattning : The aim of this project was to study what mixed cluster fragments were formed in the interaction between radiation and H2O-CO2 clusters formed by adiabatic expansion, both experimentally and using simulations. The experiment was done using a mass spectrometer at the MAX IV synchrotron facility and by studying the time-of-flight of the ionic fragments. LÄS MER

  5. 14. High Precision Robotic Manipulator for Bluelining at MAX IV

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Vinay Venkanagoud Patil; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : MAX IV is a synchrotron facility currently running 14 beamlines hosting about 1000 users per year. It is one of the best of its kind; producing high quality Xrays at the forefront of synchrotron science. To have a beamline or a synchrotron functional, every equipment used needs to be placed in the workspace with high precision. LÄS MER

  7. 15. A study of the gamma-ray emission from the blazar S50716+71 using the Fermi-LAT telescope

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Författare :Fredrik Vislander; [2022]
    Nyckelord :AGN; active galactic nuclei; Fermi-LAT; astrophysics; gamma-rays; synchrotron self-Compton; SSC; S50716 71.;

    Sammanfattning : This thesis sums up a bachelor project in which gamma-ray emission from an extra-galactic source (S50716+71) is studied using data collected by the Fermi Large Area Telescope (LAT). The emission consists of 12,5 years of data (April 2008 to February 2020) in the energy range 100 MeV - 300 GeV. LÄS MER
