  1. 16. Commissioning of the First Insertion Devices on the 1.5 GeV Storage Ring in MAX IV

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Hampus Månefjord; David Hill; [2018]
    Keywords : MAX IV; Accelerator physics; Synchrotron; light source; insertion device; Elliptically Polarized Undulator; EPU; Linear Optics from Closed Orbits; LOCO; beamline commissioning; betatron beat; undulator; wiggler; Technology and Engineering;

    Abstract : When installing an insertion device (ID) in a storage ring the electron beam is affected. The positional displacement and angle deflection is called orbit displacement (OD) and higher order effects such as focusing of the electron beam are referred to as linear optics. READ MORE

  3. 17. Application of GEANT4 toolkit for simulations of high gradient phenomena

    University essay from Uppsala universitet/FREIA; Uppsala universitet/Institutionen för teknikvetenskaper

    Author : Daniel Persson; [2018]
    Keywords : GEANT4; XBox 2; XBox; CERN; CLIC; field emission; vacuum breakdown; dark current; breakdown current; spectrometer; FREIA; accelerator; cavity;

    Abstract : To study electron emissions and dark currents in the accelerating structures in particle colliders, a test facility with a spectrometer has been constructed at CERN. This spectrometer has been simulated in the C++ toolkit GEANT4 and in this project the simulation has been improved to handle new realistic input data of the emitted electrons. READ MORE

  4. 18. Development and simulation of an active target detector with GEM foil readout

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

    Author : Elisabeth Rickert; [2017]
    Keywords : Physics and Astronomy;

    Abstract : At CERN, radioactive ion beams with energies of up to 10 MeV/u can be pro- duced by a newly commissioned post-accelerator, HIE-ISOLDE, which expands the possibilities for nuclear reaction studies. To investigate the collision properties of the ion beam with a target, an active gas–target detector is under development by the Reactions Group at the Nuclear Physics Division in Lund. READ MORE

  5. 19. Development of Method for Measuring the Beta-functions in the MAX IV Laboratory 1.5 and 3 GeV Storage Rings

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : David Olsson; [2017]
    Keywords : MAX IV; accelerator physics; accelerator; synchrotron; Technology and Engineering;

    Abstract : In any storage ring or synchrotron based light source one of the most important factors for generating light with desirable properties is the electron beam itself. The dynamics of the beam must be properly characterised and, ideally, adjusted to the desired values for the light source to be able to deliver radiation of the quality which was decided during its design.

  6. 20. Characterization of fading effects of a MOSFET semiconductor dosimeter to be used on an X-ray laser

    University essay from Stockholms universitet/Medicinsk strålningsfysik (tills m KI)

    Author : Wille Häger; [2017]
    Keywords : medical radiation physics semiconductor free-electron laser;

    Abstract : In the European XFEL, electrons bunches are accelerated up to 20 GeV and thenenter undulators where coherent X-rays are produced which can be used for imaging atva molecular level. Electrons may stray from the path and hit the permanent magnets inthe undulators. READ MORE
