  2. 1. Compact Liquid-Jet X-Ray Sources

    Author : Oscar Hemberg; KTH; []
    Keywords : liquid-jet; x-ray; EUV; plasma; electron beam; source;

    Abstract : This thesis describes the development, characterization andoptimization of compact, high-brightness, liquid-jet-targetx-ray sources. Two different source types have been developedfor different wavelength regions and applications. READ MORE

  4. 2. Liquid-Jet-Target Microfocus X-Ray Sources : Electron Guns, Optics and Phase-Contrast Imaging

    Author : Tomi Tuohimaa; Hans M. Hertz; Stephen Wilkins; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electron-impact; x-ray; brightness; liquid-jet-target; phase-contrast imaging; Engineering physics; Teknisk fysik;

    Abstract : This Thesis describes the development of an electron-impact microfocus x-ray source and its application for phase-contrast imaging. The source is based on a novel, liquid-jet target concept. Stable and continuous operation can be achieved at substantially higher electron-beam power densities than conventional solid target based systems. READ MORE

  5. 3. Electron-Impact Liquid-Jet Water-Window X-ray Sources

    Author : Peter Anders Skoglund Lindberg; Hans M. Hertz; Oscar Tjernberg; KTH; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : This Thesis describes the development and characterization of a soft x-ray liquidjet-anode electron-impact source. With a water-jet target the primary emission is the O Kα line at 525 eV. This is close to the lower edge of the water-window, a spectral region lacking simple laboratory sources. READ MORE

  6. 4. Compact Soft X-Ray Microscopy : Sources, Optics and Instrumentation

    Author : Per Takman; Hans Hertz; Janos Kirz; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; soft x-ray microscopy; water window; compact; laser plasma; liquid jet; zone plate optics; Physics; Fysik;

    Abstract : This thesis describes the development of a sub-60-nm full-period resolution compact soft x-ray microscope operating in the water-window region (2.3-4.4 nm). Soft x-ray water-window microscopy is a powerful technique for high-resolution imaging of organic materials exploiting the natural contrast mechanism between carbon and oxygen, cf. READ MORE

  7. 5. Interfaces in Dye-Sensitized Solar Cells Studied with Photoelectron Spectroscopy at Elevated Pressures

    Author : Susanna Kaufmann Eriksson; Anders Hagfeldt; Håkan Rensmo; Erik Johansson; Joachim Schnadt; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dye-sensitized solar cells; interfaces; solvation; photoelectron spectroscopy; HPXPS; HP-HAXPES; liquid jet; Chemistry with specialization in Physical Chemistry; Kemi med inriktning mot fysikalisk kemi;

    Abstract : With an increasing demand for renewable energy sources, research efforts on different solar cell technologies are increasing rapidly. The dye-sensitized solar cell (DSC) is one such technology, taking advantage of light absorption in dye molecules. READ MORE
