We treat the problem of defining the ideal x-ray refractive lens design for point focusing of low emittance x-ray beams at third- and fourth-generation synchrotron sources. The task is accomplished by using Fermat's principle to define a lens shape that is completely free from geometrical aberrations. Current microfabrication resolution limits are identified, and a design that tolerates the inherent fabrication imperfections is proposed. The refractive lens design delivers nanometer-sized…

Aberration-free aspherical lens shape for shortening the focal distance of an already convergent beam
The ideal lens surface for refocusing an already convergent beam is found to be one sheet of a Cartesian oval. This result is applied to the optimal construction of a compound refractive lens for
Development of Hard X-ray Focusing Optics at Diamond Light Source
The short wavelength of X-rays makes them an excellent choice for probing materials on the nanometer scale and for crystallography of sub-micrometer crystallites. The objective of nanofocusing optics
Ideal Cartesian oval lens shape for refocusing an already convergent beam
Nanofocusing compound refractive lenses (CRLs) have short focal lengths and hence require many refracting surfaces to be lined up along the optical axis. The usual spherical or parabolic refracting
CVD Diamond and Nanodiamond: Versatile Materials for Countering a Wide Range of CBRN Threats
Fabrication of thin films of diamond by chemical vapour deposition (CVD) has now developed into a mature technology, with high-quality diamond readily available from multiple vendors at relatively

Single-element elliptical hard x-ray micro-optics.
Using micro-fabrication techniques, a single element kinoform lens in single-crystal silicon with an elliptical profile for 12.398 keV (1A) x-rays is manufactured, resulting in a one micron line focus at the National Synchrotron Light Source X13B beamline.
Focusing hard x rays to nanometer dimensions by adiabatically focusing lenses.
We address the question of what is the smallest spot size that hard x rays can be focused to using refractive optics. A thick refractive x-ray lens is considered, whose aperture is gradually
Aspherical lens shapes for focusing synchrotron beams.
The Cartesian oval, a lens shape that produces perfect point-to-point focusing for monochromatic radiation, is studied in the context of X-ray beamlines, and optical surfaces that approximate ideal shapes are compared.
Hard x-ray nanoprobe based on refractive x-ray lenses
Based on nanofocusing refractive x-ray lenses a hard x-ray scanning microscope is currently being developed and is being implemented at beamline ID13 of the European Synchrotron Radiation Facility
Diamond kinoform hard X-ray refractive lenses: design, nanofabrication and testing.
Progress in designing, nanofabricating and testing of diamond kinoform refractive lenses for synchrotron X-ray radiation studies and tests of the focusing action at the APS 8-ID-I beamline are focused on.
Using compound kinoform hard-x-ray lenses to exceed the critical angle limit.
The data demonstrate that it is possible to exceed the critical angle limit by using multiple lenses, while retaining lens function, and this suggests a route to practical focusing optics for hard x-ray photons with nanometer scale resolution and below.
Large-acceptance diamond planar refractive lenses manufactured by laser cutting.
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.
Nanofocusing of hard X-ray free electron laser pulses using diamond based Fresnel zone plates
This work demonstrates the first nanofocusing of hard XFEL pulses, and develops diamond based Fresnel zone plates capable of withstanding the full beam of the world's most powerful x-ray laser.
On the feasibility of large-aperture Fresnel lenses for the microfocusing of hard X-rays.
The best Fresnel lenses in this study are found to provide experimentally more than 50% of the expected refraction efficiency at 8.5 keV photon energy, which is almost identical to that of perfect Be CRLs with the same focal length.
High efficiency nano-focusing kinoform optics for synchrotron radiation.
Silicon micro-technology has so far provided some of the most advanced x-ray refractive lenses; this work reports on design and characterisation of a novel silicon kinoform lens that is capable of delivering nano-beams with high efficiency.
