A modification of the of high-speed high-resolution X-ray absorption spectroscopy (Quick Extended X-ray Absorption Fine Structure, QEXAFS) method based on an adaptive bending element of X-ray optics is described. This technique was implemented at the Langmuir station of the Kurchatov Synchrotron Radiation Source (KISI-Kurchatov). The absorption spectrum of a model sample, bromine in a sodium bromide compound, was recorded. A recording speed up to 5 seconds per spectrum was achieved in the continuously recording regime. The method is applicable for obtaining information about both the structure and dynamics of a wide range of objects, ordered and disordered, in any aggregate state.
