This system enables transmission-mode X-ray absorption fine structure (XAFS) measurements and X-ray emission spectroscopy (XES) measurements that are typically made at a synchrotron to be made in the lab. The instrument is made possible with modern x-ray optics and detectors, a 1.2 kW XRD-type tube (either Mo or Ag) for XAFS, and a 100 W XRF-style tube for XES (either W or Pd). Most of the beam path is in a He environment to maximize flux at the sample. Transmission samples are mounted over a ~12 mm x 2 mm area, and an automatic sample changer with seven spots is available. One possible sample preparation procedure might include powdering and homogeneously mixing with polyethylene glycol to form a pellet with a thickness corresponding to ~1 absorption length just over the absorption edge of interest. Due to the lower flux compared to a synchrotron, more care than for synchrotron measurements can be required.<\/span><\/p>\n<p style=\"text-align: justify\"><span style=\"color: #000000\">Specifications:<\/span><\/p>\n<ul style=\"text-align: justify\">\n<li><span style=\"color: #000000\">Measurement Mode: XAFS and XES<\/span><\/li>\n<\/ul>\n<ul style=\"text-align: justify\">\n<li><span style=\"color: #000000\">XAFS X-ray Source, Mo or Ag: 1.2 kW liquid-cooled x-ray tube<\/span><\/li>\n<li><span style=\"color: #000000\">XES X-ray Source, W or Pd: 100 W air-cooled x-ray tube<\/span><\/li>\n<\/ul>\n<\/td>\n<td style=\"width: 1.07875%;height: 300px\"><\/td>\n<td style=\"width: 49.5016%;height: 300px\">&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<img class=\"size-medium alignnone\" src=\"https:\/\/wpcdn.web.wsu.edu\/wp-labs\/uploads\/sites\/99\/2025\/04\/easyEXAFS-396x377.png\" width=\"396\" height=\"377\" \/>\n<p><img class=\"size-medium alignnone\" src=\"https:\/\/wpcdn.web.wsu.edu\/wp-labs\/uploads\/sites\/99\/2025\/04\/easyEXAFS2-396x296.png\" width=\"396\" height=\"296\" \/><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<ul style=\"text-align: justify\">\n<li><span style=\"color: #000000\">Energy Range: 5-~20 keV.<\/span>\n<ul>\n<li><span style=\"color: #000000\">See figures below for available edges.
