Abstract
We present results of focusing X-rays in a configuration suitable for a time-resolved X-ray absorption fine structure (XAFS) measurement in the microsecond range, an improvement by two orders of magnitude over previous techniques at synchrotron sources. The approach employs a new method of focusing X-rays by confinement and combines it with flow techniques from laser technology. The inexpensive focusing method provided a line focus of about 10 μm with intensity gains of at least 9, which produced quality XAFS spectra of a 58 millimolar solution of zinc sulfate in a fast flowing jet stream.
