Main Research Techniques:
X-ray Absorption Spectroscopy (XAS), Energy Dispersive EXAFS (EDE), X-ray Emission Spectroscopy
I18 Microfocus spectroscopy
B18 Core EXAFS
Please Note: The scanning branch of I20 will be accepting new proposals in the AP14 call, which covers the period from Oct 2013-March 2014.The operational energy range of the beamline covers 5keV to 20keV that is defined by the installed Si(111) monochromator crystals. We will be accepting proposals for x-ray absorption spectroscopy experiments in transmission and fluorescence mode (using the 64 elements germanium monolithic detector), and also for the emission spectrometer that operates in the energy range from 6keV to 15keV. A commissioning call for the dispersive branch of I20 will be open later in the year.
This beamline covers three very distinctive modes of operation: 1) X-ray Absorption Spectroscopy (XAS) on challenging samples, 2) Energy Dispersive EXAFS (EDE), and 3) X-ray Emission Spectroscopy.
I20 is equipped with two wigglers in the same straight section, one for the scanning branch and the other for the dispersive branch. The scanning branch offers monochromatic x-rays with high flux and high spectral purity in energy resolution and harmonic content for transmission and fluorescence measurements. The dispersive branch will be optimised for in-situ time-resolved x-ray spectroscopy studies.
I20 will support a wide range of applications, especially in biology, environmental science, chemistry and materials science.
