  1. 1. Vacuum Ultraviolet Scanning Photoelectron Microscopy, Instrumentation & Applications

    Författare :Ulf Johansson; Lunds universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Photoelectron Microscopy; Spectromicroscopy; Photoemission; Silicon; Oxide desorption; High-Tc superconductor; Physics; Ellipsoidal mirror; Fysik; Chemistry; Kemi; Fysicumarkivet A:1997:Johansson;

    Sammanfattning : This thesis describes the design and characterisation of a vacuum ultraviolet scanning photoelectron microscope as well as results from studies of laterally inhomogeneous surfaces. The instrument utilises synchrotron radiation from an undulator at the 550 MeV storage ring at the MAX-laboratory. LÄS MER

  3. 2. Plasma Modification of Polypropylene Materials for Improved Adhesion

    Författare :Anna Nihlstrand; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; polypropylene; characterization; material composition; lacquer adhesion; plasma modification; chain scission; vacuum-ultraviolet radiation; thermoplastic polyolefin;

    Sammanfattning : Materials based on PP are widely used in industrial applications. To fulfil application demands, components must often be lacquered, printed or glued. As PP is highly unreactive and presents a low surface energy, a pretreatment that can promote bondability is necessary. LÄS MER

  4. 3. Multi-Electron Coincidence Studies of Atoms and Molecules

    Författare :Egil Andersson; Raimund Feifel; Jan-Erik Rubensson; Kiyoshi Ueda; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; multi-ionization; electron emission; time-of-flight spectroscopy; coincidence spectroscopy; core-valence ionization; synchrotron radiation; electron correlation; Atomic and molecular physics; Atom- och molekylfysik; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Sammanfattning : This thesis concerns multi-ionization coincidence measurements of atoms and small molecules using a magnetic bottle time-of-flight (TOF) spectrometer designed for multi-electron coincidence studies. Also, a time-of-flight mass spectrometer has been used together with the TOF electron  spectrometer for electron-ion coincidence measurements. LÄS MER

  5. 4. Experimental Techniques for Studies in Atomic & Molecular Physics

    Författare :Filip Heijkenskjöld; Jan-Erik Rubensson; Peder Royen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; spectroscopy; fast ion beam laser spectroscopy; time of flight photoelectron photoelectron coincidence; hyperfine structure; Rabi oscillation; Physics; Fysik;

    Sammanfattning : This thesis is based on a selection of six different experimental techniques used for studies in atomic and molecular physics. The techniques analysed in the thesis are compared to find similarities in strategies and ways to avoid sources of error.Paper 1 deals with collision based spectroscopy with 60 keV Xe6+ ions on sodium and argon gas targets.
