We present evidence for the rst observation of electromagnetically bound π±K∓pairs (πK-atoms) with the DIRAC experiment at the CERN-PS. The πK-atoms are produced by the 24 GeV/c proton beam in a thin Pt-target and the π± and K∓mesons from the atom dissociation are analyzed in a two-arm magnetic spectrometer. The observed enhancement at low relative momentum(More)
The aim of this study was to evaluate the feasibility of phase-contrast mammography with synchrotron radiation using a high-resolution computed radiology (CR) system devoted to mammography. The study was performed at the Synchrotron Radiation for Medical Physics (SYRMEP) beamline of the Elettra synchrotron radiation (SR) facility in Trieste (Italy); X-ray(More)
The goal of the DIRAC experiment at CERN (PS212) is to measure the π+π− atom lifetime with 10% precision. Such a measurement would yield a precision of 5% on the value of the S-wave ππ scattering lengths combination |a0 − a2|. Based on part of the collected data we present a first result on the lifetime, τ = [2.91+0.49 −0.62] × 10−15 s, and discuss the(More)
X-Ray Phase Contrast Imaging (XPCI) has been arguably the hottest topic in X-ray imaging research over the last two decades, due to the significant advantages it can bring to medicine, biology, material science and many other areas of application. Considerable progress has recently been achieved, in terms of the first in vivo implementations at synchrotrons(More)
In this note, we present preliminary results of a research activity concerning the measurement of fibres orientation distribution in inj ection moulded short fibre reinforced polymer composites. The proposed measure is based on the Mean Intercept Length (MIL) parameter, commonly used in biomechanics, obtained from the analysis of three-dimensional images(More)
