Nuclear multilayer structure with antireflecting coating
Gusev M.V., Chumakov A.I., Smirnov G.V.
A combined application of resonant Bragg diffraction by nuclear multilayer structure and specular antireflection by coating film to provide a beam of synchrotron radiation with super narrow ΔΕ/Ε 10~" bandwidth is studiedA proposed structure includes two antireflecting films above and below the nuclear multilayer. Computer simulation shows the possibility to reach a high nuclear reflectivity with a suppression of electronic scattering down to 4 · 10~7 at the angular position of nuclear Bragg reflection.
