  1. 1. Electron beam sizes and lifetimes at MAX II and MAX III

    Författare :Anders Rosborg; Lunds universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Electron accelerator; Storage ring; Synchrotron light source; Synchrotron radiation; Electron beam profile; Emittance; Beam size; Fysicumarkivet A:2012:Hansson; Lifetime; Bunch length; Landau cavities;

    Sammanfattning : The MAX II and MAX III synchrotron light sources at MAX-lab provide synchrotron radiation for experiments in a wide variety of research fields. The synchrotron radiation is emitted by ultra-relativistic electrons circulating in electron storage rings. LÄS MER

  3. 2. Beam Diagnostics and Dynamics in Nonlinear Fields

    Författare :Jim Ögren; Roger Ruber; Volker Ziemann; Klaus Leifer; Stephen Peggs; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Beam diagnostics; Nonlinear beam dynamics; Accelerator physics;

    Sammanfattning : Particle accelerators are indispensable tools for probing matter at the smallest scales and the improvements of such tools depend on the progress and understanding of accelerator physics. The Compact Linear Collider (CLIC) is a proposed, linear electron–­positron collider on the TeV-scale, based at CERN. LÄS MER

  4. 3. Electron beam profile measurements and emittance manipulation at the MAX-laboratory

    Författare :Åke Andersson; Lunds universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; optics; quantum excitation; emittance; synchrotron radiation; electron beam; lattice; Accelerator; storage ring; diffraction; Physics; Fysik;

    Sammanfattning : The emittances of the electron beams at the MAX-laboratory accelerator system have been studied. Apart from the build-up of the diagnostic tools for precise determination of the beam spatial profiles, the objectives have been: a) to verify the accelerator design emittances at low currents and to try to determine the emittances also at high currents; b) to investigate possibilities to manipulate the emittances.

  5. 4. Monitoring and control of laser beam butt joint welding

    Författare :Morgan Nilsen; Anna-Karin Christiansson; Fredrik Sikström; Michael Schmidt; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laser beam welding; Optical sensors; Joint tracking; Varying gap; Manufacturing and materials engineering; Produktions- och materialteknik;

    Sammanfattning : Laser beam welding is one important technology in automated production. It has several advantages, such as the ability to produce deep and narrow welds giving limited heat induced deformations. The laser beam welding process is however sensitive to how the high power laser is positioned with regards to the joint position. LÄS MER

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