Journal ArticleDOI
On the possibilities of x-ray phase contrast microimaging by coherent high-energy synchrotron radiation
TL;DR: In this paper, a straightforward experimental setup for phase contrast imaging is proposed and used to record holographic images from organic samples of 10-100 pm at energy lo-50 keV with the contrast up to 50%-100%.
Journal ArticleDOI
Large-acceptance diamond planar refractive lenses manufactured by laser cutting
Maxim Polikarpov,Maxim Polikarpov,Irina Snigireva,John Morse,V. Yunkin,Sergey Kuznetsov,Anatoly Snigirev +6 more
TL;DR: For the first time, single-crystal diamond planar refractive lenses have been fabricated by laser micromachining in 300 µm-thick diamond plates which were grown by chemical vapour deposition to withstand the extreme flux densities expected at the planned fourth-generation X-ray sources.
Journal ArticleDOI
X-ray multilens interferometer based on Si refractive lenses.
TL;DR: A multilens X-ray interferometer consisting of six parallel arrays of planar compound refractive lenses, each of which creates a diffraction limited beam under coherent illumination, produces an interference pattern demonstrating substantially strong longitudinal functional dependence.
Journal ArticleDOI
Linear parabolic single-crystal diamond refractive lenses for synchrotron X-ray sources
Sergey Terentyev,Maxim Polikarpov,Irina Snigireva,Marco Di Michiel,S. I. Zholudev,V. Yunkin,Sergey Kuznetsov,Vladimir Blank,Anatoly Snigirev +8 more
TL;DR: Linear parabolic diamond refractive lenses are presented, designed to withstand high thermal and radiation loads coming from upgraded accelerator X-ray sources.
Journal ArticleDOI
Short-focus silicon parabolic lenses for hard X-rays
V.V. Aristov,V.V. Starkov,Leonid Shabel'nikov,Sergey Kuznetsov,A.P. Ushakova,M. Grigoriev,V.M. Tseitlin +6 more
TL;DR: In this paper, a photoanodic etching of silicon in the form of profiles 22 μm deep and 5 μm in diameter was used to construct a lens with a focal length of 7 cm and image resolution of 3 μm.
