Title: Acoustic excitation of the circular Bragg{endash}Fresnel lens in backscattering geometry

Abstract

An increment of the x-ray flux in crystal Bragg{endash}Fresnel lens (BFL) focus in backscattering geometry obtained by means of acoustic excitation of the BFL crystal substrate has been investigated. The dependence of the x ray{close_quote}s total reflected power versus ultrasound parameters has been studied in a low frequency range (10{endash}50 MHz). The proposed technique allows an increase in the flux in a BFL focus by a factor of 2 which almost achieves the kinematic limit. {copyright} {ital 1997 American Institute of Physics.}
