ID22: a multitechnique hard X-ray microprobe beamline at the European Synchrotron Radiation Facility.
The ID22 beamline is dedicated to hard X-ray microanalysis allowing the combination of fluorescence, spectroscopy, diffraction and tomography techniques in a wide energy range from 6 to 70 keV. The recent installation of an in-vacuum undulator, a new sample stage and the adaptation of various focusing optics has contributed to a great improvement in the capabilities of the beamline, which is no...
متن کاملPhase Analysis and Focusing of Synchrotron Radiation
High accuracy calculations of synchrotron radiation (SR) emitted by a relativistic electron show that the phase of the frequency domain electric field of SR differs from the phase of radiation of a virtual point source. These differences may result in the reduction of focusing efficiency of diffraction-limited SR, if the focusing is performed by conventional optical components optimised for poi...
متن کاملNanofocusing optics for synchrotron radiation made from polycrystalline diamond.
Diamond possesses many extreme properties that make it an ideal material for fabricating nanofocusing x-ray optics. Refractive lenses made from diamond are able to focus x-ray radiation with high efficiency but without compromising the brilliance of the beam. Electron-beam lithography and deep reactive-ion etching of silicon substrates have been used in a transfer-molding technique to fabricate...
متن کاملSagittal focusing of synchrotron radiation X-rays using a winged crystal
A Si(111) winged crystal has been designed to minimize anticlastic bending and improve sagittal focusing efficiency. The crystal was thin with wide stiffening wings. The length-to-width ratio of the crystal was optimized by finite element analysis, and the optimal value was larger than the `golden value'. The analysis showed that the slope error owing to anticlastic bending is less than the Dar...
متن کاملComparison of focusing optics for femtosecond X-ray diffraction
We characterize and compare four different types of focusing optics for hard X-rays, suitable for femtosecond X-ray diffraction experiments, using a tabletop femtosecond laser-based plasma source. We demonstrate a 23μm focus with a toroidally bent Ge single crystal. A maximum flux of 7 × 108 photons/(s mm2) is generated in a 32μm focus using a multi-layer mirror. An elliptical glass capillary y...
