    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Nanofabrication; Zone plate; x-ray; diffractive x-ray optics; x-ray microscopy; Optics; Optik; Physics; Fysik;

    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

  3. 3. Laboratory x-ray fluorescence tomography

    Author : Jakob C. Larsson; Hans Hertz; Anna Burvall; Ulrich Vogt; Norbert Pelc; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; x-ray; fluorescence; x-ray fluorescence; nanoparticle; xrf; xfct; tomography; Fysik; Physics;

    Abstract : X-ray fluorescence (XRF) tomography is an emerging bio-imaging modality with potential for high-resolution molecular imaging in 3D. In this technique the fluorescence signal from targeted nanoparticles (NPs) is measured, providing information about the spatial distribution and concentration of the NPs inside the object.

    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

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

    Author : Lars Rymell; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; 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
