  2. 11. Materials analysis using MeV-ions: fundamental challenges and in-situ applications

    Author : Karim-Alexandros Kantre; Daniel Primetzhofer; Hans-Christian Hofsäss; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; in-situ characterization; ion beam analysis; heavy ions; reactive thin film growth; materials modification; yttrium oxyhydrides; fuel retention;

    Abstract : The interaction of energetic ions with matter is highly relevant for a wide range of applications. Amongst them, material characterization employing ion beams is widely used due to its capability of high-resolution composition depth profiling. READ MORE

  4. 12. Beam loss mechanisms in relativistic heavy-ion colliders

    Author : Roderik Bruce; Lunds universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The Large Hadron Collider (LHC), the largest particle accelerator ever built, is presently under commissioning at the European Organization for Nuclear Research (CERN). It will collide beams of protons, and later Pb ions, at ultrarelativistic energies. READ MORE

  5. 13. Laser-driven beams of fast ions, relativistic electrons and coherent x-ray photons

    Author : Olle Lundh; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plasma Acceleration of Electrons and Ions; Advanced Accelerator Concepts; X-ray Lasers; Intense Beams and Radiation Sources; Intense Laser-Plasma Interactions;

    Abstract : This thesis presents experimental results on the development and optimization of novel and highly compact sources of beams of fast ions, relativistic electrons and coherent x-rays, driven by intense laser-plasma interactions. The rapid development of high-power, short-pulse laser systems have made available peak powers reaching the petawatt regime and focused intensities reaching 10^21 W/cm2. READ MORE

  6. 14. Minuscular sculpturing

    Author : Greger Thornell; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; materialvetenskap; Materials Science;

    Abstract : Most of the processes employed in microstructure technology have been adopted from the fabrication scheme of integrated circuits (IC). Although being extremely reliable and cost efficient, they suffer from poor material and geometrical flexibility. READ MORE

  7. 15. 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.
