In recent years, x-ray radiography has been used to probe the internal structure of dense sprays. Quantitative measurements of spray mass distribution have been obtained on microsecond time scales and with spatial resolution of 15 μm even in high-pressure environments. These data have been difficult or impossible to obtain with conventional optical diagnostics. A limitation to these measurement...

Spatial resolution tests were performed on beamline 1.4.4 at the Advanced Light Source in Berkeley, CA, USA, a third-generation synchrotron light source. This beamline couples the high-brightness synchrotron source to a Thermo-Electron Continumicrom XL infrared microscope. Two types of resolution tests were performed in both the mid-IR and near-IR. The results are compared with a diffraction-li...

For a bunched beam, coherent energy spread generated within a bending system may couple to the transverse (bending) plane coordinates through the chromatic transfer functions of the particular beamline—even an achromatic beamline. The resulting transverse emittance dilution is dependent on the magnitude of the energy spread, its generation rate along the beamline, and the beamline’s chromatic t...

Powder X-ray diffraction techniques largely benefit from the superior beam quality provided by high-brilliance synchrotron light sources in terms of photon flux and angular resolution. The High Resolution Powder Diffraction Beamline P02.1 at the storage ring PETRA III (DESY, Hamburg, Germany) combines these strengths with the power of high-energy X-rays for materials research. The beamline is o...

Abstract A soft x-ray reflectivity beamline is operational on Indus-2 synchrotron source since 2016 for reflectivity, transmission and absorption measurements in 100-1500 eV photon energy range. To perform spectroscopic experiments 60-1000 spectral range a emission spectrometer (SXES) designed which will serve as an additional experimental station the beamline. The SXES setup using aberration c...

For analysis of lithium ion batteries, the ultra soft X-ray absorption spectroscopy beamline BL-2 at SR center of Ritsumeikan University has been improving: adding the new grating (900 l/mm) to the monochromator for higher energy up to 1000eV, and constructing the XAFS-PES (photoelectron spectroscopy) chamber equipped with in-situ transfer vessel systems. To elucidate the performance of this be...

In collaboration with GSI Biophysics, the microbeam, operated with ions from the UNILAC linear accelerator of GSI, is routinely employed for targeted irradiation of living cells in culture [1]. A custom-made fluorescence microscope is used both for beam targeting and for cell observation via fluorescent dyes that specifically highlight the biological agent of interest. Green Fluorescent Protein...

The calculation for the optics of the synchrotron radiation small and wide angle x-ray scattering beamline, currently under construction at SESAME is described. This beamline is based on a cylindrically bent germanium (111) single crystal with an asymmetric cut of 10.5 degrees , followed by a 1.2 m long rhodium coated plane mirror bent into a cylindrical form. The focusing properties of bent as...
