  1. 1. 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

  2. 2. Time-resolved x-ray diffraction of nanostructured samples

    University dissertation from Stockholm : KTH

    Author : A. I. H. Persson; Lunds universitet.; Lund University.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; x-ray diffraction; phonons; optoacoustic transducer; electron diffusion; nanowires; Fysicumarkivet A:2016:Persson;

    Abstract : The work presented in this thesis is based on time-resolved x-ray diffraction studies of InSb (111) samples. The experiments were carried out using a pump-probe configuration using short laser pulses as the pump and x-rays as the probe. Laser excitation leads to the formation of a strain pulse that propagates through the sample. READ MORE

  3. 3. A Structural Viewpoint of Magnetism in Fe and Co Based Superlattices

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Matts Björck; Uppsala universitet.; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Magnetism; Multilayer; Superlattice; X-ray magnetic circular dichroism; X-ray diffraction; X-ray reflectivity; Neutron diffraction; Structural refinement; Interfaces; Fysik;

    Abstract : In order to understand the properties of thin film devices, knowledge of the material's structure is essential. The work presented here combines magnetic and structural characterization of the systems studied to gain a deeper physical understanding. READ MORE

  4. 4. Compact Soft X-Ray Microscopy: Image Processing and Instrumentation

    University dissertation from Stockholm : KTH

    Author : Heide Stollberg; KTH.; [2006]

    Abstract : Soft x-ray microscopy is a powerful technique for natural-contrast, high-resolution imaging of organic materials. This Thesis describes new instrumentational and new image-processing methods to improve the image quality of the compact x-ray microscope at the Biomedical & X-Ray Physics division at KTH. READ MORE

  5. 5. Growth and Nano-structural Studies of Metallic Multilayer for X-ray Mirrors

    University dissertation from Institutionen för fysik, kemi och biologi
