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.}

Bragg{endash}Fresnel optics for hard x-ray microscopy: Development of fabrication process and x-ray characterization at the Advanced Photon Source

Journal Article Li, Y ; Wong, G C ; Safinya, C R ; ... - Review of Scientific Instruments

Results are presented on development of processes for fabricating linear and circular Bragg{endash}Fresnel lenses (BFLs) on Si and III{endash}V compound material substrates, and on x-ray characterization of linear BFLs at the Advanced Photon Source (APS). Processes were developed for fabricating long (zone length {gt}5 mm) linear BFLs on Si with enhanced capability for focusing high-energy x rays. By stitching together 20 sequentially exposed 400-{mu}m-long linear BFLs, we were able to fabricate 8-mm-long linear BFLs with 0.5-{mu}m finest zone width. BFLs were also fabricated on III{endash}V compound semiconductor substrates GaAs and InP, with improved process control due to the substantially reducedmore »« less

Ion implanted Bragg{endash}Fresnel lens

Journal Article Souvorov, A ; Snigirev, A ; Snigireva, I ; ... - Review of Scientific Instruments

We have investigated the feasibility of widening the bandpath of the Bragg{endash}Fresnel optical element through the use of ion implantation. The focusing properties of Bragg{endash}Fresnel lenses (BFLs) were studied as a function of the implantation dose and energy. An enhancement of the focus intensity of up to 15{percent} was found, which is less than expected. Due to the complicated scattering of the low energy ions inside the micrometer- and submicrometer-sized crystal features that make up the BFL relief, the implantation technology destroys the peripheral zones of the BFL more than it increases the intensity in the focus. Nevertheless we believemore »« less

A Linear Single-Crystal Bragg-Fresnel Lens With SiO2 Surface Structure

Journal Article Kuznetsov, S ; Yunkin, V ; Drakopoulos, M ; ... - AIP Conference Proceedings

Bragg-Fresnel lens (BFL) as thin silicon dioxide strips grown on the surface of perfect silicon crystal was designed, manufactured and experimentally tested. In this case the BFL structure consists of a set of silicon dioxide rectangular shape etched zones arranged by the Fresnel zone law. The stress within coated and uncoated crystal regions is opposite in sign, whether tensile or compressive. The strain in the substrate crystal lattice directly underneath discontinuities in the deposited film give rise to phase difference between waves diffracted from coated and uncoated crystal regions. This phase difference is known to be dependent on the thicknessmore »« less

Synchrotron radiation focusing by a Bragg--Fresnel lens

Journal Article Aristov, V V ; Basov, Y A ; Snigirev, A A - Rev. Sci. Instrum.; (United States)

Since the discovery of x rays and until the present time the possibilities of their controlling and focusing have been widely discussed. In the hard spectrum region (/lambda//similar to/1 A) the main focusing schemes are the following: geometrical focusing based on incoherent interaction of wave packets reflected by different regions of bending crystals and coherent (dynamic) focusing performed at the cost of the effect of refraction index angular dispersion near the exact Bragg angle value /minus//theta//sub /ital B//. A main disadvantage of geometrical focusing is low spatial resolution (/similar to/0.1 mm) and temperature stability. In the case of coherent focusingmore »« less

Characterizing the hard x-ray diffraction properties of a GaAs linear Bragg-Fresnel lens

Journal Article Li, Youli ; Wong, Gerard C. L. ; Case, Ryan ; ... - Applied Physics Letters

We investigated the diffractive focusing properties of (111) GaAs linear Bragg-Fresnel lenses (BFLs) developed for hard x-ray microscopy and microdiffraction of complex materials in confined geometries. We demonstrated that the use of GaAs yields significant processing advantages due to the reduced zone depth. Focal plane diffraction patterns of linear BFLs measured at the advanced photon source using 8-40 keV x rays were compared to a simple model based on Kirchhoff-Fresnel diffraction theory. Good agreement was obtained between experimental data and model calculations using only zones within an effective aperture defined by the transverse coherence of the source.
