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

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

    Sammanfattning : 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. LÄS MER

  2. 2. Particle Phenomenology of Compact Extra Dimensions

    Författare :Henrik Melbéus; Tommy Ohlsson; Andrea Romanino; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Higher-dimensional quantum field theories; universal extra dimensions; Arkani-Hamed–Dimopolous–Dvali ADD model; hierarchy problem; Kaluza– Klein dark matter; neutrino mass; seesaw mechanism; leptonic mixing; renormalization group running; collider phenomenology; Large Hadron Collider;

    Sammanfattning : This thesis is an investigation of the subject of extra dimensions in particle physics. In recent years, there has been a large interest in this subject. In particular, a number of models have been suggested that provide solutions to some of the problem with the current Standard Model of particle physics. LÄS MER

  4. 4. Laser-Driven Particle Acceleration - Improving Performance Through Smart Target Design

    Författare :Matthias Burza; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; wakefield; ultra-relativistic; ultra-intense; TNSA; Terawatt; sheath; proton; polarimetry; plasma mirror; plasma; Petawatt; particle; oscillation; Normarski; micromachining; LWFA; laser; interferometry; electron; contrast; acceleration; bubble; Fysicumarkivet A:2012:Burza;

    Sammanfattning : Laser-driven particle acceleration makes use of sub-picosecond, pulsed, high-power laser systems, capable of producing intensities ~10^{19} W/cm^2 at the laser focus to form plasmas, and use ultra-relativistic and nonlinear dynamics to produce quasistatic acceleration fields. This allows electrons to be accelerated to ~100 MeV over sub-centimetre distances, while protons may be accelerated to the ~10 MeV regime. LÄS MER
