  1. 220. Phase sensitive mammographic imaging at the SYRMEP beamline
    Prof. Renata Longo (Università di Trieste - Dipartimento di Fisica)

    Applications
    Oral presentation
    The phase sensitive imaging methods can be assigned to one of three broad categories namely, x-ray interferometry, diffraction-enhanced imaging (DEI), and in-line phase-contrast imaging (PhC). Using these techniques the gradient or the Laplacian of the x-ray phase is acquired and therefore the density variation and interfaces are emphasized. Phase maps can be obtained by some methods.

  2. 160. A Fast Neutron Scintillation Detector in Homeland Security Applications
    Dr Giovanna Davatz (Arktis Radiation Detectors Ltd)

    Applications
    Oral presentation
    A neutron scintillation detector based on high-pressure He-4 has been developed and demonstrates excellent response to elastic scattering of fast neutrons. The detector removes the need for moderation allowing the preservation of neutron spectral information. Neutrons from three different sources, AmBe, Cf-252, and from the ambient background, have been measured with clearly distinct energy...

  3. 121. Detection of explosive materials with Gamma Resonant Nuclear Absorption and Argon-Nitrogen TPC
    Dr Igor Kreslo (LHEP, Uni-Bern)
    07/07/2011, 09:25
    Oral presentation
    Detection of explosives in large cargo containers is an important preventive measure to counteract terrorism. The element-sensitive radiography with gamma-rays is one promising method, allowing to selectively detect Nitrogen content in various materials, which is a reliable signature of most of commercial explosives. A novel high-resolution tracking detector sensitive to 9.17 MeV Nitrogen...

  4. 205. An electronic detector to replace film for Electron Cryomicroscopy?
    Dr Wasi Faruqi (MRC Laboratory of Molecular Biology, Hills Road, Cambridge CB2 0QH, U.K./Institute for Experimental and Applied Physics, CTU in Prague, Prague 2, Czeck Republic.)

    Applications
    Oral presentation
    Electron cryomicroscopy (cryoEM) is of immense importance in macro-molecular structural determination to as near atomic resolution as possible. Some recently reported structures using cryo-EM have reached 0.33 nm resolution, similar to what can be obtained with X-ray crystallography. A great deal of high resolution cryoEM data is still collected on film, which has excellent resolution,...

  5. 123. Direct detection, high frame rate, radiation-hard CMOS monolithic pixels for high resolution Transmission Electron Microscopy
    Devis Contarato (Lawrence Berkeley National Laboratory)
    07/07/2011, 10:05
    Applications
    Oral presentation
    CMOS monolithic active pixel sensors are rapidly becoming an established technology for digital imaging in Transmission Electron Microscopy. Direct electron detection, with sensitivity down to single electrons, benefits the sensor Detective Quantum Efficiency (DQE), while Modulation Transfer Function (MTF) and ultimately single point resolution are greatly enhanced by the thin sensitive layer...
