The Total-Reflection X-Ray Fluorescence Yield Formed by a Waveguide Resonator under Conditions of Ion Beam Excitation

The features of methods for total-reflection X-ray fluorescence analysis with proton-induced X‑ray fluorescence emission are described. A setup for obtaining X-ray fluorescence spectra under the conditions of proton-beam excitation has been developed using these methods. The setup is based on a specially designed planar X-ray waveguide resonator. The features of the new experimental diagnostic method in the unique research facility (UNU no. 45) of the Sokol-3 analytical ion-beam complex are discussed; some attention has been paid to the description of the capabilities of this facility.
