  2. 1. From Macroscopic to Microscopic Dynamics of Superconducting Cavities

    Author : Anirban Bhattacharyya; Vitaliy Goryashko; Volker Ziemann; Roger Ruber; Jean Delayen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; superconducting cavity; superconductivity; self-excited loop; Ginzburg-landau; vortex; optimization; quality factor; microwave; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

    Abstract : Superconducting (SC) radio frequency (RF) cavities are at the heart of many large-scale particle accelerators such as the European Spallation Source (ESS), the X-ray Free Electron Laser (XFEL), the Linac Coherent Light Source (LCLS)-II and the proposed International Linear Collider (ILC). The SC cavities are essentially resonant structures with very high intrinsic quality factors (Q0) of the order of 1010. READ MORE

  4. 2. Timing Modes for the MAX IV Storage Rings

    Author : Teresia Olsson; Lunds universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Synchrotron light storage rings; timing experiments; ultralow emittance; harmonic cavities; fill patterns; PPRE; PSB; Fysicumarkivet A:2018:Olsson;

    Abstract : The MAX IV facility includes two storage rings, operated at 1.5 and 3 GeV energy, for the purpose of producing high-brilliance synchrotron radiation for users. The 1.5 GeV ring replaces the previous MAX II and MAX III storage rings as a source of UV and soft X-rays, whereas the 3 GeV ring is optimized for hard X-rays. READ MORE

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

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

    Abstract : 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. READ MORE

  6. 4. Electron beam sizes and lifetimes at MAX II and MAX III

    Author : Anders Rosborg; Lunds universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  7. 5. Cavity Field Control for Linear Particle Accelerators

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

    Abstract : 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. READ MORE
