  2. 1. Synchrotron radiation from runaway electrons in plasmas

    Author : Adam Stahl; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; runaway electrons; critical electric field; fusion plasma physics; tokamak; synchrotron radiation;

    Abstract : Highly relativistic runaway electrons are of great concern in the area of fusion energy research, since their presence in tokamak plasmas have the potential to hinder the successful and stable operation of the device, and potentially cause severe structural damage. In this thesis, runaway electron generation dynamics is investigated using the newly developed efficient computational tool CODE. READ MORE

  5. 3. Optical Properties of Single Silicon Quantum Dots

    Author : Federico Pevere; Jan Linnros; Uwe Kortshagen; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; silicon; nanocrystals; quantum dots; photoluminescence; optics; emission; absorption; Fysik; Physics;

    Abstract : For over 60 years silicon (Si) has dominated the semiconductor microelectronics industry mainly due to its abundance and good electrical and material properties. The advanced processing technology of Si has made it the workhorse for photovoltaics industry as well. READ MORE

  6. 4. Multi-messenger emission from gamma-ray bursts

    Author : Filip Samuelsson; Felix Ryde; Peter Mészáros; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; astrophysics; gamma-ray bursts; cosmic rays; Atomic; Subatomic and Astrophysics; Atomär fysik; subatomär fysik och astrofysik;

    Abstract : Multi-messenger astronomy is a very hot topic in the astrophysical community. A messenger is something that carries information. Different astrophysical messenger types are photons, cosmic rays, neutrinos, and gravitational waves. They all carry unique and complementary information to one another. READ MORE

  7. 5. Soft X-ray Emission Spectroscopy of Liquids and Lithium Battery Materials

    Author : Andreas Augustsson; Joseph Nordgren; Jinghua Guo; Kevin Smith; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Atomic and molecular physics; Soft X-ray emission; resonant inelastic X-ray scattering; lithium battery; electronic structure; liquid water; Atom- och molekylfysik; Atomic and molecular physics; Atom- och molekylfysik;

    Abstract : Lithium ion insertion into electrode materials is commonly used in rechargeable battery technology. The insertion implies changes in both the crystal structure and the electronic structure of the electrode material. READ MORE
