1. Development of capillary optics for X-ray focusing
Sammanfattning : .... LÄS MER
2. Laboratory x-ray fluorescence tomography
Sammanfattning : 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. LÄS MER
3. X-ray Phase Contrast Tomography : Setup and Scintillator Development
Sammanfattning : X-ray microscopy and micro-tomography (μCT) are valuable non-destructive examination methods in many disciplines such as bio-medical research, archaeometry, material science and paleontology. Besides being implemented at synchrotrons radiation sources, laboratory setups using an X-ray tube and high-resolution scintillation detector routinely provide information on the micrometre scale.

4. Nanofabrication of Diffractive Soft X-ray Optics
Sammanfattning : 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. LÄS MER
5. Laboratory soft x-ray microscopy and tomography
Sammanfattning : 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. LÄS MER
