  1. 1. Fast retuning of superconducting radiofrequency accelerating cavities in the European Spallation Source linear accelerator.

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Sofia Johannesson; [2020]
    Nyckelord :Accelerator; retuning; ESS; Technology and Engineering;

    Sammanfattning : The aim of the degree project is to continue the work of PhD student YuanShuai Qin on creating a fast retuning of the ESS accelerator lattice in the event of an accelerating cavity being offline. The main goal of the project was evaluating and improving the retuning routine created by YuanShuai Qin. LÄS MER

  3. 2. A Linear Framework for Orbit Correction in the High-Luminosity Large Hadron Collider

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Joel Andersson; [2019]
    Nyckelord :CERN; HL-LHC; LHC; accelerator physics; orbit correction; error correction; closed orbit; Twiss; beam dynamics; dynamical systems; Python; Mathematics and Statistics;

    Sammanfattning : In a circular accelerator the closed orbit can be viewed as the mean position of particles in a beam. The closed orbit is perturbed by machine errors and can be manipulated by dedicated corrector magnets. LÄS MER
