Speaker
Description
The MEX1 beamline high resolution crystal spectrometer, spectroMEX, comprises a Johann-type point-to-point focusing geometry crystal spectrometer employing five spherically bent crystals on a 0.5 m diameter Rowland circle. The primary application of spectroMEX is high energy resolution fluorescence-detected (HERFD) XANES, wherein fluorescence XANES is collected with an energy resolution of the order of the core-hole lifetime broadening. HERFD XANES spectra contain additional spectral information when compared to conventional fluorescence or transmission XANES. spectroMEX also facilitates collection of high quality x-ray emission spectroscopy data, including the weak, but chemically sensitive valence-to-core emission lines (vtc-XES). This talk will describe the spectroMEX spectrometer design, progress to date, and present examples of the new spectroscopic techniques available to synchrotron users employing spectroMEX at the MEX1 beamline.
