1. 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.

2. Soft X-rays and secondary electrons : Velocity measurements on the electron emission produced by soft X-rays and by electron impact
Sammanfattning : .... LÄS MER
3. Refractive Optics for Hard X-rays
Sammanfattning : .... LÄS MER
4. Very thin magnets : X-rays, lasers and spectroscopy
Sammanfattning : The magnetic properties of transition metal films are investigated using synchrotron based x-ray absorption and x-ray photoelectron spectroscopy. These techniques are elementally selective and may therefore be used, either to probe a specific element in a multicomponent system or, as very sensitive magnetometers. LÄS MER
5. Cellular responses to combined irradiation with alpha particles and X-rays
Sammanfattning : Mixed radiation fields, where different ionizing particles act together, are very important in radiobiology and in radiation protection. Mixed beams are not only the most common form of radiation exposure, but the prediction of their biological effect is also full of uncertainties. LÄS MER
