Applying for beamtime at the AS MEX1 and MEX2 beamlines

If you answer “NO” to any of these questions; STOP. Go back and take the necessary steps to answer “YES”, otherwise your proposal is likely uncompetitive.

“We will measure 64 ex-situ powder pellet samples at the MEX-1 beamline, (i) 13 powder standards of Br and Zn, and (ii) 51 samples in powder form sourced from our experiments conducted at XXX University. These samples will be produced at XXX University using a variety of treatment conditions and tested at the beamline ex-situ.
We will measure the K edges for Br and Zn calibrated with Zn metallic foil, as K edges for Br and Zn fall at 13,473.7 eV and 9,658.6 eV, using Si(111) monochromator in step scan. The sample environment will be room temperature and under helium. We will aim to operate step scan and will dilute the samples with cellulose to approximately 1000 ppm of the target element for fluorescence-mode measurements, or OR to an edge step in the range of XX for transmission mode. These The mixtures will be made homogeneous using a mortar and pestle, compressed into a 7 mm diameter pellet using a hand press and mounted on a MEX-1 PMMA sample holder. Data will be collected to reach K = XXX for EXAFS with duplicate scans.”
