  1. 1. Prospects for a Free Electron Laser at the FemtoMAX Beamline

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Johan Holmberg; [2024]
    Keywords : Free Electron Lasers; FEL; synchrotron radiation; MAX IV; FemtoMAX; GENESIS 1.3; XFEL; X-rays; soft X-rays; Physics and Astronomy;

    Abstract : A Free Electron Laser (FEL), is a device that generates extremely coherent and brilliant radiation using electrons accelerated to relativistic velocities in a particle accelerator. The process utilises similar equipment to what is used at a synchrotron source like MAX IV, but in addition there is an interaction between the relativistic electron beam and the generated radiation to achieve an exponential growth in radiation intensity.

  3. 2. Generation of attosecond X-ray pulses in free-electron lasers using electron energy modulation and undulator tapering

    University essay from Uppsala universitet/FREIA

    Author : Karl-Fredrik Boholm Kylesten; [2023]
    Keywords : attosecond; free-electron laser; XFEL; self-amplified spontaneous emission; SASE; tapering; energy modulation;

    Abstract : Free-electron lasers (FELs) are among the world's most intense artificial artificial sources of coherent light and are tunable to various wavelengths, including the X-ray spectrum. X-ray FELs (XFELs) are extremely useful for diffraction experiments to study molecules, materials, and quantum systems. READ MORE

  4. 3. Simulations of stray radiation in the European XFEL undulators with the Geant4 toolkit

    University essay from Stockholms universitet/Fysikum

    Author : Guillermo Lopez Basurco; [2022]
    Keywords : Geant4; Monte Carlo simulations; XFEL undulators; gamma radiation flux;

    Abstract : The European XFEL is an X-ray free electron laser research facility that generates ultrashort, high intensity flashes. Three SASE undulator systems are made of undulator segments and intersection components. READ MORE

  5. 4. A Near-Infrared Diffraction Radiation Spectrometer for MHz Repetition Rate Electron Bunch Diagnostics at the European XFEL

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Simon Fahlström; [2019]
    Keywords : European XFEL; XFEL; Free-Electron Laser; FEL; bunch diagnostics; Coherent Diffraction Radiation; Spectrometer;

    Abstract : We have built a spectrometer to investigate the Near-Infrared (NIR) range of this radiation, which is used for bunch diagnostics at the European X-ray Free-Electron Laser. This could give information on the development of microbunching, periodic features in the longitudinal charge profile of the bunches which have a negative impact on the operation of the facility.

  6. 5. Investigation of the origin of stray radiation at XFEL using FLUKA

    University essay from Stockholms universitet/Fysikum

    Author : Terese Hellström; [2019]
    Keywords : ;

    Abstract : The European X-Ray Free-Electron Laser facility (XFEL) provides ultra-short x-ray pulsesof high peak brilliance that are used in research to analyse atomic or molecular structures.The facility accelerates electrons and moves them through an undulator system consistingof several undulator cells containing permanent magnet poles supplying an alternatingmagnetic field, which causes the electrons to emit x-ray pulses.
