    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; magnetic resonance; supraconductors; relaxation; spectroscopy; magnetic and optical properties; rare-gas clusters; Condensed matter:electronic structure; electrical; metal clusters; photoemission; synchrotron radiation; core-level spectroscopy; Auger decay; XPS; nano-particles; free clusters; egenskaper elektriska; spektroskopi; magnetisk resonans; magnetiska och optiska ; supraledare; Kondenserade materiens egenskaper:elektronstruktur;

    Sammanfattning : The main topic of this Thesis is the x-ray spectroscopic studies of free nano-clusters with size more than 10^3 atoms. The photoelectron spectroscopy experiments on rare gas and metal clusters were performed at beamline I411 at MAX-lab National Swedish synchrotron radiation facility. Free rare-gas clusters are simplest objects in cluster research. LÄS MER

  3. 3. Optical Studies For Synchrotron Radiation Beamlines

    Detta är en avhandling från MAX IV Laboratory, Lund University

    Författare :Walan Grizolli; Lunds universitet.; Lund University.; [2015]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Optics; Synchrotron Radiation; X-ray Optics; Beamline; Polarimetry; Coherence; Storage Rings; Diffraction Limited Storage Rings;

    Sammanfattning : Synchrotron radiation sources have greatly contributed to the progress in many fields of science. The development of the storage ring technologies has made possible to obtain very low emittance electron beams, which together with the use of undulators allow guiding a very high photon flux into a very small spot required by the experiments.

  4. 4. Studies of Molecular and Cluster Fragmentation Using Synchrotron Radiation: Measurements and Models

    Detta är en avhandling från MAX IV Laboratory, Lund University

    Författare :Andreas Lindgren; Lunds universitet.; Lund University.; [2006]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Atomic and molecular physics; Atom- och molekylärfysik; photoionization; synchrotron radiation; localized excitation; electron-ion coincidence; induced alignment; clusters; molecules; core excitation; mass spectroscopy; fragmentation; dissociation;

    Sammanfattning : A new spectrometer for studying photoinduced fragmentation has been designed and commissioned. The instrument produces a detailed view of the energy and angular emission of fragments, which in the case of small molecules can be related to their geometry at the moment of dissociation. LÄS MER

  5. 5. Small science on big machines: Politics and practices of synchrotron radiation laboratories

    Detta är en avhandling från MAX IV Laboratory, Lund University

    Författare :Olof Hallonsten; Lunds universitet.; Lund University.; [2009]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; little science; big science; sophistication; collectivization; European Synchrotron Radiation Facility; Stanford Synchrotron Radiation Lightsource; MAX-lab; scientific entrepreneurs; changing dynamics of science; Synchrotron radiation; research policy; science policy;

    Sammanfattning : Synchrotron radiation laboratories are large scientific facilities where various scientific experiments are carried out by the use of radiation produced by particle accelerators. Research with synchrotron radiation emerged in the 1960s and 1970s as a peripheral activity at particle physics laboratories. LÄS MER
