  1. 16. Verification measurements on MRI-linac with PTW BEAMSCAN MR

    University essay from Umeå universitet/Institutionen för fysik

    Author : Olivia Kvarnlöf; [2022]
    Keywords : ;

    Abstract : In radiotherapy the main goal is to kill cancer cells, prevent them from growing and reproducing, while healthy tissue is spared. One technique to treat cancer is to use external radiotherapy where a linear accelerator (linac) is used to generate a high energy radiation photon beam. READ MORE

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

    University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

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

    Abstract : 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. READ MORE

  4. 18. Prompt emission in Gamma-ray bursts; Photospheric Radiation from Synchrotron-Like spectra

    University essay from KTH/Fysik

    Author : Erik Vitols; [2022]
    Keywords : Gamma-ray burst; radiation mechanisms: thermal and non-thermal;

    Abstract : Gamma-ray bursts (GRBs) are the most luminous phenomena in the Universe, explosions whoseenergy is generated by supernovae or mergers of dense objects such as neutron stars. The GRBemission is divided into the prompt emission phase characterized by γ-ray radiation and the afterglowof lower energy radiation. READ MORE

  5. 19. Constructing and commissioning of a Multi-Grid neutron detector prototype for the European Spallation Source

    University essay from Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen; Lunds universitet/European Spallation Source ESS AB

    Author : Rebecka Wahlén; [2022]
    Keywords : Physics and Astronomy;

    Abstract : A prototype of a novel 10B-based neutron detector called the Multi-Grid detector has been constructed, tested and commissioned for the European Spallation Source (ESS). The detector is constructed after the specifications set by the CSPEC instrument at ESS and is therefore called the CSPEC Multi-Grid detector. READ MORE

  6. 20. Thermal neutron counting and gamma-ray peak identification from fusion reactions, using a Sodern Genie-16 Neutron Generator

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

    Author : Auden Ti; [2022]
    Keywords : Physics and Astronomy;

    Abstract : This thesis work focuses on the categorisation of a Sodern Genie-16 Neutron Generator, at the Nuclear Applications Laboratory, Lund University. To that end, the goals of this work focuses on the re-development of the pre-existing infrastructure surrounding the Sodern Genie-16 Neutron Generator for the purposes of internally irradiating samples, and the subsequent categorisation of the new configuration for extraction of fast neutrons.
