    Abstract : Soft x-ray microscopy in the water-window (λ = 2.28 nm – 4.36 nm) is based on zone-plate optics and allows high-resolution imaging of, e.g. READ MORE

  2. 2. Phase-Contrast and High-Resolution Optics for X-Ray Microscopy

    University dissertation from Stockholm : KTH

    Author : Olof von Hofsten; KTH.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Microscopy; X-ray optics; X-ray microscopy; Soft X-ray physics; NATURAL SCIENCES Physics Other physics Optics; NATURVETENSKAP Fysik Övrig fysik Optik; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik;

    Abstract : X-ray microscopy is a well-established technique for nanoscale imaging. Zone plates are used as microscope objectives and provide high resolution, approaching 10 nm, currently limited by fabrication issues. This Thesis presents zone plate optics that achieve either high resolution or phase contrast in x-ray microscopy. READ MORE

    Abstract : This thesis summarizes the present status of the nanofabrication of diffractive optics, i.e. zone plates, and test objects for soft x-ray microscopy at KTH. The emphasis is on new and improved fabrication processes for nickel and germanium zone plates. READ MORE

  4. 4. A new laser-plasma X-ray source for microscopy and lithography

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Lars Rymell; Lund University.; Lunds universitet.; [1997]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; X-ray microscopy; X-ray lithography; Atomic and molecular physics; multilayer mirror; Fysicumarkivet A:1997:Rymell; Atom- och molekylärfysik; X-ray source; Laser-produced plasma; liquid droplet; debris-free; water window;

    Abstract : A new high-brightness source for soft X-rays and EUV-radiation has been developed. This laser-plasma source utilizes a microscopic liquid droplet or jet as target. The result is a reduction of debris emission by several orders of magnitude compared to conventional laser plasmas. READ MORE

  5. 5. Compact Soft X-Ray Microscopy Sources, Optics and Instrumentation

    University dissertation from Stockholm : KTH

    Author : Per Takman; KTH.; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; soft x-ray microscopy; water window; compact; laser plasma; liquid jet; zone plate optics; NATURAL SCIENCES Physics; NATURVETENSKAP 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
