DEVICE FOR X-RAY-FLUORESCENT ANALYSIS OF MATERIALS WITH FLUX GENERATION BY FLAT X-RAY WAVEGUIDE-RESONATOR Russian patent published in 2015 - IPC G01N23/223 

FIELD: physics.

SUBSTANCE: this device comprises primary X-ray radiation source and excitation flux generator. Analysed material specimen fitted on holder is arranged inside excitation flux generator parallel with direction of propagation of this flux. X-ray fluorescent radiation detector is located opposite specimen holder with specimen fitted thereon. Excitation flux generator is composed of a flat X-ray waveguide-resonator with clearance between reflectors of nano-sized magnitude. Note also that said generator has hole to introduce analysed material in specimen flux so that its analysed surface is located in reflector plane located opposite aforesaid detector. Besides it incorporates radiation recorder detector located at waveguide-resonator outlet. Said detector allows positioning of this device relative to primary radiation source. Note here that specimen holder can displace independently of waveguide-resonator in direction perpendicular to direction of excitation radiation flux propagation. Radiation recoding detector can register radiation that passed through waveguide-resonator and control the specimen input to excitation radiation flux.

EFFECT: controlled feed of specimen to excitation radiation flux.
