  1. 6. Nonlinear Optics Studies on the MAX IV Storage Rings

    Författare :David K Olsson; Lunds universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; accelerator physics; synchrotron; storage ring; magnetic optics; non-linear optics; characterisation; optimisation;

    Sammanfattning : The MAX IV Laboratory in Lund, Sweden, houses two electron storage rings operating at the energies 1.5, and 3 GeV. Both of these produce high-brilliance synchrotron radiation for beamline users. While the 1. LÄS MER

  3. 7. Criticality of fast failures in the High Luminosity Large Hadron Collider

    Författare :Björn Lindström; Roger Ruber; Daniel Wollmann; Maja Olvegård; Annika Nordt; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; machine protection; failures; beam losses; accelerator physics;

    Sammanfattning : Each of the two Large Hadron Collider (LHC) beams contain 362 MJ of energy. This will be further increased to 678 MJ in the upcoming upgrade to the High Luminosity LHC (HL-LHC). In the event of an uncontrolled beam loss, a significant hazard occurs, that can damage the machine components. LÄS MER

  4. 8. Efficiency Enhancement Techniques for Free-Electron Lasers

    Författare :Alan Mak; Lunds universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; free-electron laser; accelerator physics; efficiency enhancement; undulator tapering; phase jump method; synchrotron radiation; Fysicumarkivet:2017:Mak;

    Sammanfattning : The central question addressed in this thesis is how to make the free-electron laser (FEL) more efficient. In recent years, coherent diffraction imaging provides an important motivation for efficiency enhancement. This is because a more efficient FEL process enables converting a larger fraction of the electron beam's power into optical power. LÄS MER

  5. 9. Beam-Based Error Identification and Correction Methods for Particle Accelerators

    Författare :Tobias Persson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Emittance; Accelerator Optics; LHC; Pulse Compressor; Feedback; Two-beam acceleration; Accelerators; CLIC; Radio Frequency; CTF3;

    Sammanfattning : Modern particle accelerators have tight tolerances on the acceptable deviation from their desired machine parameters. The control of the parameters is of crucial importance for safe machine operation and performance. This thesisfocuses on beam-based methods and algorithms to identify and correct errors in particle accelerators. LÄS MER
