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

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

   Sammanfattning : 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. LÄS MER

3. 2. Compact Soft X-Ray Microscopy : Sources, Optics and Instrumentation

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

   Sammanfattning : 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. LÄS MER

4. 3. Compact Soft X-Ray Microscopy

   Författare :Göran Johansson; KTH; []
   Nyckelord :soft x-ray microscopy; laser plasma; multilayer optics; water window; zone plate optics;

   Sammanfattning : This thesis describes the development of soft x-rayreflective optics, instrumentation and applications for compactsoft x-ray microscopy. The microscope is based on a table-topliquid-jet-target laser-plasma source in combination with aspherical normal-incidence multilayer condenser mirror andnanofabricated diffractive optics for imaging.
