A new FReLoN (Fast-Readout Low-Noise) high-frame-rate detector adopted for the fast continuous collection of X-ray absorption spectra is presented. The detector is installed on the energy-dispersive X-ray absorption beamline ID24 at the ESRF and is capable of full time-resolved EXAFS spectra collection with over 4kHz repetition rate and 0.2ms exposure time. An example of the in situ kinetic study of the high-temperature oxidation of metallic iron is presented.
