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

   Author : A. I. H. Persson; Atomfysik; []
   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

4. 2. Design of a Total-Reflection X-Ray Fluorescence Spectrometer and Application to Periphyton Communities

   Author : Patrik Pettersson; Chalmers tekniska högskola; []

   Abstract : Properties of magnetic thin film devices cannot be understood without detailed knowledge of their structure. For this purpose, a variety of thin film and multilayer systems have been studied. READ MORE

6. 4. Multilayer X-ray mirrors for water window wavelengths

   Author : Fredrik Eriksson; Linköpings universitet; []
   Keywords : ;

   Abstract : This thesis describes the design, growth and x-ray characterization of normal incidence multilayer x-ray mirrors. The mirrors are intended as condenser optics for soft x-ray microcsopy in the water window.A droplet-target laser-plasma soft x-ray source has been developed to be used in a compact soft x-ray microscope.
