  2. 11. Applications of Laser-Plasma Acceleration

    Author : Kristoffer Svendsen; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; laser wakefield acceleration; betatron radiation; X-rays; X-ray imaging; phase-contrast imaging; VHEE; radiotherapy; radiography; fuel injector; tomography; beam focusing; atomizing sprays; nanowires; liquid mass; target normal sheath acceleration; applications; charged particles;

    Abstract : This thesis is dedicated to the investigation of laser-plasma particle acceleration concepts. Some of the work was focused on improving electron and proton acceleration for future applications, in terms of maximizing the particle energy and minimizing the divergence of the X-ray beams.

  4. 12. Laser-Driven Plasma Waves for Particle Acceleration and X-ray Production

    Author : Guillaume Genoud; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Laser plasma acceleration of electrons and protons; laser-wakefield acceleration; plasma waves; plasma-wiggler radiation; betatron radiation; laser guiding; laser pointing stabilisation;

    Abstract : This thesis presents experimental results related to laser plasma accelerators. These rely on very different principles from conventional particle accelerators. READ MORE

  5. 13. Emittance and Energy Diagnostics for Electron Beams with Large Momentum Spread

    Author : Maja Olvegård; Volker Ziemann; Kay Wittenburg; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; beam instrumentation; particle beam diagnostic; emittance; particle collider; particle accelerator; High Energy Physics; Högenergifysik;

    Abstract : Following the discovery of the Higgs-like boson at the Large Hadron Collider, there is demand for precision measurements on recent findings. The Compact Linear Collider, CLIC, is a candidate for a future linear electron-positron collider for such precision measurements. READ MORE

  6. 14. Energy Conversion and Particle Acceleration at Turbulent Plasma Jet Fronts

    Author : Louis Richard; Yuri V. Khotyaintsev; Tomas Karlsson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : High speed plasma flows (jets) are ubiquitous phenomena in the universe. For example, they carry energy from the most powerful sources (e.g active galactic nucleï AGN) to the medium at rest surrounding them. READ MORE

  7. 15. Tilted Foils Nuclear Spin Polarization at REX-ISOLDE

    Author : Hans Törnqvist; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; beta-NMR; ISOLDE; tilted foils; particle scattering; post-acceleration; REX-ISOLDE; nuclear spin polarization; HIE-ISOLDE;

    Abstract : This thesis will explain and summarize my work and involvement in experiments aimed at producing nuclear spin polarization of post-accelerated beams of ions with the tilted-foils technique at the REX-ISOLDE linear accelerator at CERN. Polarizing the nuclear spin of radioactive beams in particular may provide access to observables which may be difficult to obtain otherwise. READ MORE
