SAMBA a New Beamline at SOLEIL for XRay Absorption Spectroscopy in the 440keV Energy Range

Phytoavailability of lead altered by two Pelargonium cultivars grown on contrasting lead-spiked soils

“…Spectra from extended X-ray absorption fine structure (EXAFS) spectroscopy were recorded at the Pb L III -edge (13.055 keV) at the French National Synchrotron Facility (SOLEIL, St. Aubin, France) on the SAMBA beam line equipped with a Si(111) double crystal monochromator (Belin et al 2005). The bulk spiked soil was dried, ground in an agate mortar, and pressed as 5-mm-diameter pellets using a hydraulic press generating a pressure of 30 bars.…”

High thermoelectric figure of merit in well optimized YbyCo4Sb12

“…The chemical composition of the samples in set2 was determined by Electron Probe Micro Analysis (EPMA, CAMECA SX100). X-ray absorption spectroscopy was carried out on the SAMBA beamline 43 at SOLEIL synchrotron source, using a fixed sagitally focusing Si(111) double crystal monochromator. XANES spectra were recorded in transmission mode, in the 8800-9000 eV energy range (including LIII-Yb edge), with a 0.3eV resolution in the edge jump, at five different temperatures: 20 K, 70 K, 130 K, 200 K and 300 K. Spectra were normalized using the MAX-Package 44 .…”

SAMBA: The 4–40 keV X-ray absorption spectroscopy beamline at SOLEIL

“…The mirrors are used over the whole 4-40 keV energy range available on SAMBA by tilting the mirrors from 10 mrad to 1 mrad depending on the desired cut-off energy for removing the harmonic X-rays [5]. The reflective Pd surfaces are 1200 mm long per 88 mm wide allowing a horizontal acceptance of ∼6.2 mrad on the first collimating mirror located at 14.1 m from the source.…”
