  1. 1. Cavity Field Control for Linear Particle Accelerators

    Detta är en avhandling från Department of Automatic Control, Lund Institute of Technology (LTH)

    Författare :Olof Troeng; [2019-11-05]
    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

  2. 2. Cavity Field Control for High-Intensity Linear Proton Accelerators

    Detta är en avhandling från Department of Automatic Control, Lund Institute of Technology, Lund University

    Författare :Olof Troeng; [2017-06-07]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Particle Acceleration; Automatic Control; European Spallation Source;

    Sammanfattning : The European Spallation Source will, once fully operational in 2025, be the world's brightest neutron source. The neutrons will be generated by bombarding a tungsten target with protons accelerated to 96\% the speed of light by electromagnetic fields confined in 155 radio-frequency cavities along the world's most powerful linear accelerator.

  3. 3. Migration of Sea Turtles from Caribbean Costa Rica: Implications for Management

    Detta är en avhandling från Ekologiska institutionen, Lunds universitet

    Författare :Sebastian Troëng; [2005]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Animal ecology; conservation; predation; remigration; annual survival probability; mtDNA; satellite telemetry; tagging; Costa Rica; Tortuguero; endangered; migration; Djurekologi; sea turtles;

    Sammanfattning : Tortuguero National Park in Costa Rica hosts nesting by four species of highly migratory and endangered sea turtles (green, hawksbill, leatherback and loggerhead turtles). Sea turtle research at Tortuguero has been continuous since Dr. Archie Carr began studies in the 1950?s. LÄS MER
