  1. 11. Radiation Effects on GaN-based HEMTs for RF and Power Electronic Applications

    University essay from KTH/Tillämpad fysik

    Author : Wilhelm Holmberg; [2023]
    Keywords : High Electron Mobility Transistor; HEMT; Gallium Nitride; GaN; Silicon Carbide; SiC; Proton Radiation; Galliumnitrid; GaN; Kiselkarbid; SiC; Kisel; Si; HEMT; Transistor; Protonstrålning;

    Abstract : GaN-HEMTs (Gallium Nitride-based High Electron Mobility Transistors) have, thanks to the large band gap of GaN, electrical properties that are suitable for applications of high electrical voltages, high currents, and fast switching. The large band gap also gives GaN-HEMTs a high resistance to radiation. READ MORE

  3. 12. Developing an ML-based model for RF tuning of the DTL machine at ESS

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Amin Hosseini Nejad; [2023]
    Keywords : Technology and Engineering;

    Abstract : The European Spallation Source (ESS) infrastructure is being constructed in Lund, and will be one of the most powerful research facilities of its type in the world. The ESS linear accelerator (linac) utilizes different accelerating sections where a wide variety of techniques should be employed to accelerate a beam of protons to 2 GeV kinetic energy through Radio Frequency (RF) cavities before being collided with a tungsten target for the final production of neutrons, through the process of spallation.

  4. 13. Neutron backgrounds in neutrino-nucleus scattering at the European Spallation Source

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

    Author : José Guilherme Rodrigues de Albuquerque Vale; [2023]
    Keywords : Neutrino-nucleus scattering; background; PHITS; weight window; ESS; Physics and Astronomy;

    Abstract : Being, when built, the most powerful neutron accelerator in the world, there will be a large number of potential discoveries at the European Spallation Source (ESS) in Lund. One of the most exciting of these, from a particle physics point of view, is the Coherent Elastic Neutrino-Nucleus Scattering (CEνNS). READ MORE

  5. 14. Navigating New Norms : The Transformation of Leadership in Hybrid Work Setting

    University essay from Malmö universitet/Institutionen för Urbana Studier (US)

    Author : Rick Eckerholm; [2023]
    Keywords : Leadership; Remote leadership; Future leadership; Hybrid work; Virtual work environment ;

    Abstract : Background: The traditionally homogeneous work environment, historically associated with physical locations such as offices and buildings, has undergone significant changes in recent years. This change has been driven by technological innovation, cultural development and external challenges, an accelerator in this process was the global spread of covid-19, which radicalized the traditional way of working.

  6. 15. Generation of attosecond X-ray pulses in free-electron lasers using electron energy modulation and undulator tapering

    University essay from Uppsala universitet/FREIA

    Author : Karl-Fredrik Boholm Kylesten; [2023]
    Keywords : attosecond; free-electron laser; XFEL; self-amplified spontaneous emission; SASE; tapering; energy modulation;

    Abstract : Free-electron lasers (FELs) are among the world's most intense artificial artificial sources of coherent light and are tunable to various wavelengths, including the X-ray spectrum. X-ray FELs (XFELs) are extremely useful for diffraction experiments to study molecules, materials, and quantum systems. READ MORE
