  1. 1. X-ray Phase Contrast Tomography : Setup and Scintillator Development

    Author : Hanna Dierks; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; x-rays; x-ray imaging; x-ray microscopy; X-ray detectors; perovskites; laboratory setups; phase contrast; μCT; scintillator; Phase contrast PC ; Tomography x-ray computed ;

    Abstract : 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. 4. Very thin magnets : X-rays, lasers and spectroscopy

    Author : Jonathan Hunter Dunn; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Physics; Fysik; fysik; Physics;

    Abstract : 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. READ MORE

  5. 5. Cellular responses to combined irradiation with alpha particles and X-rays

    Author : Alice Sollazzo; Andrzej Wojcik; Alexandros Georgakilas; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Radiation; DNA damage; mutations; alpha particles; X-rays; mixed beam; molekylär biovetenskap; Molecular Bioscience;

    Abstract : 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. READ MORE
