XAFS measurement system using undulator synchronized on-the-fly monochromator scan at SPring-8 BL36XU [PDF]

Journal of Synchrotron Radiation
In X-ray absorption fine structure (XAFS) measurements at undulator beamlines, it has been difficult to simultaneously achieve both spectral time resolution and high X-ray flux that fully utilizes the optical performance of the beamline. To overcome this
