  1. 182. XRF Imaging Based on Polycapillary Optics
    Prof. Kouichi Tsuji (Osaka City University)
    27/09/2016, 11:20
    Oral presentation
    Kouichi Tsuji, Shota Aida, and Yuki Takimoto Graduate School of Engineering, Osaka City University (OCU), 3-3-138 Sugimoto, Sumiyoshi-ku, Osaka 558-8585, Japan A non-destructive elemental imaging is important for environmental, forensic, and material sciences. We will introduce a few approaches for x-ray elemental and chemical imaging in the laboratory at OCU. The drawback of the...

  2. 196. 2D-3D μXRF Elemental Mapping Reconstruction on Archeological Samples
    Dariush Hampai (LNF)
    27/09/2016, 11:50
    Oral presentation
    "Rainbow X-Ray" (RXR) is a μXRF station at "XLab-Frascati", now open for users and optimized for any kind of analytical research field using X-ray sources. In collaboration with two archeological groups (site "Grotta Romanelli" - Late Pleis- tocene, and site "Gran Carro" - Iron Age) we are starting X-ray Fluorescence studies on local artifacts. The elemental analysis of these artifacts (in...

  3. 112. X-ray radiation for beam diagnostics
    Dr Alexander Shchagin (Kharkov Institute of Physics and Tecknology)
    27/09/2016, 12:05
    Oral presentation
    For many years, the optical transition radiation (OTR) was successfully applied for beam diagnostics. However, distortions of the OTR images appear at decreasing of the beam size and increasing of beam current because of diffraction and coherent effects. The influence of these effects can be suppressed using the radiation in the X-ray range. In the present paper, the possible...

  4. 148. Focusing properties of X-ray radiation channeling at the exit of a MCP
    Augusto Marcelli (LNF)
    27/09/2016, 12:20
    Oral presentation
    Capillary optics is a basic X-ray technology capable to deliver a high flux density within a sub-micrometer spot. This compact optics could be easily used both to guide and to shape an intense X-ray beam within a small spot, a low divergence and with a high homogeneity. Arrays of curved tapered capillaries (polycapillary optics) can be used to focus, collimate, and filter x-ray radiation [1]....

  5. 167. Characterization of Non-Gaussian beam profiles of polycapillary lenses
    Mr Marcel Bremekamp (Helmut Fischer GmbH Intitut fuer Elektronik und Messtechnik)
    27/09/2016, 12:35
    Oral presentation
    Polycapillary x-ray optics are a powerful tool to focus x-ray radiation in order to achieve small spot sizes of about ~10 µm. Especially the capability to focus radiation in a broad energy range (5-30 keV) shows polycapillary x-ray optics to be without an alternative for compact table-top EDXRF spectrometers. Since their invention in the early 1990s, a lot of developments were made and many...

  6. 38. Simultaneous K-edge subtraction tomography for strontium tracer using parametric X-ray radiation
    Prof. Yasushi Hayakawa (Laboratory for Electron Beam Research and Application (LEBRA), Nihon University)
    27/09/2016, 12:50
    Oral presentation
    The X-ray source based on parametric X-ray radiation (PXR) has been regularly providing a coherent X-ray beam for application studies at Nihon University. Recently, three dimensional (3D) computed tomography (CT) is one of the most important applications of the PXR source. In particular, the methodology referred to as K-edge subtraction (KES) imaging is a typical application utilizing the...
