X-ray fluorescence analysis of heavy elements with a portable synchrotron

X-ray fluorescence analysis of heavy elements was performed using a portable synchrotron named MIRRORCLE. Analyzed heavy elements were Pb, Pt, W, Sn, and Ag. The characteristic K X-rays were clearly observed for all the five elements. This verifies that MRRORCLE generates X-rays of energy higher than that of the Pb K absorption edge (88.0 keV). In addition to these characteristic K X-rays, several peaks with short lifetimes were also observed in all the elements.
