  1. 1. Optics Corrections and Stabilization Methods for Particle Accelerators

    Författare :Tobias Persson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LHC; accelerators; beam optics; ; feedback; CTF3; optics correction; CLIC;

    Sammanfattning : The discovery of a Higgs-like particle is the result of excellent performance ofboth the LHC (Large Hadron Collider) and its detectors. A significant partof the success can be attributed to the excellent control of the optics in theaccelerator. In this thesis the methods used to correct the optics functions arepresented. LÄS MER

  3. 2. 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

  4. 3. Accelerators for Physics Experiments : From Diagnostics and Control to Design

    Författare :Elena Wildner; Thomas Lindblad; Mikael Eriksson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Astroparticle physics; Astropartikelfysik;

    Sammanfattning : This thesis develops techniques of control-methods, optimization, and diagnostics of accelerator equipment and the produced particle beams with emphasis on the Large Hadron Collider (LHC) project at CERN. From a solid knowledge of the characteristics of the manufactured accelerator equipment gained from in-depth measurements and analysis of measured data, a link to an enhanced equipment design can be made.

  5. 4. Cavity Field Control for Linear Particle Accelerators

    Författare :Olof Troeng; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Particle accelerators; Cavity field control; LLRF; Complex-coefficient systems; Q design; Disturbance-rejecting peak filters;

    Sammanfattning : High-energy linear particle accelerators enable exploration of the microscopic structure of pharmaceuticals, solar cells, fuel cells, high-temperature superconductors, and the universe itself. These accelerators accelerate charged particles using oscillating magnetic fields that are confined in metal cavities. LÄS MER

  7. 5. A Finance Model for the Built Cultural Heritage - Proposals for improvements of future Heritage Economics

    Författare :Ingela Pålsson Skarin; Bebyggelsevård; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Finance Model; Built Cultural Heritage; Heritage Economics; Accelerators; Emotional Accelerator; Financial Accelerator;

    Sammanfattning : Abstract The new role of built cultural heritage, as an economic asset for development strategies and the widened definition of built heritage as a concept-, explains today’s affluence of sites. These can only be guaranteed with sufficient heritage funding. LÄS MER
