QEXAFS spectroscopy

The final point raised in Section 5 is also repeated. In QEXAFS spectroscopy it is not usual that the scans need to be collected faster, but that the data quality needs to be higher, so that detailed structural information can be derived. This goal will likely be achieved in the future by the improved design of beam line optics, more experiments being performed on undulator or wiggler beam lines, and improvements in detector technology. 

Typically X-ray absorption spectroscopy can be measured in situ in two ways, that is, transmission or fluorescence/emission. Normally the in situ time-resolved approach demands that a number of data must be collected in a short time period. Data can be obtained typically with (sub)second-minute time resolution using quick XAS techniques (QEXAFS), which scan across and above an absorption edge by moving a monochromator incrementally and fast (160).
