  2. 1. Spectroscopic Investigations of Highly Charged Tungsten Ions - Atomic Spectroscopy and Fusion Plasma Diagnostics

    Author : Joel Clementson; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; extreme ultraviolet spectra; spheromak; electron beam ion trap; magnetic fusion; tungsten; highly charged ions; atomic structure; x-ray spectroscopy; plasma diagnostics; Fysicumarkivet A:2010:Clementson;

    Abstract : The spectra of highly charged tungsten ions have been investigated using x-ray and extreme ultraviolet spectroscopy. These heavy ions are of interest in relativistic atomic structure theory, where high-precision wavelength measurements benchmark theoretical approaches, and in magnetic fusion research, where the ions may serve to diagnose high-temperature plasmas.

  4. 2. Atomic Spectroscopy for Applications in Energy Technology

    Author : Thomas Lennartsson; Astronomi - Genomgår omorganisation; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; atomic structure; plasma diagnostics; branching fractions; gas discharges; highly charged ions; extreme ultraviolet spectra; time-resolved spectroscopy;

    Abstract : This thesis intends to provide spectroscopic information which may be of use in the investigation of low-density plasmas. Developed since the 19th century, the spectroscopic approach has proven to be a versatile method for measuring properties in hot gases, such as electron and ion temperatures and densities, the abundance of various elements in the gas, etc. READ MORE

  5. 3. Short Attosecond Pulse Trains at High Repetition Rates for Novel Pump-Probe and Coincidence Studies

    Author : Sara Mikaelsson; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Attosecond; High-Order Harmonic Generation; Photoionization; Attosecond; High-Order Harmonic Generation; Photoionization; Fysicumarkivet A:2021:Mikaelsson;

    Abstract : This work aims at studying photoionization dynamics from atoms and surfaces at attose time scales. The work was based on development and applications of a high repetition rate High-order Harmonic Generation (HHG) light source that utilizes Optical Parametric Amplification (OPA) laser technology.
