Beam Splitters

A novel fabrication process was proposed to produce high-quality Bragg beam splitters for hard X-ray free-electron lasers (XFELs), which should consist of thin, bend-free, and robust Bragg-case crystals without any defects. A combination of a mechanical process and plasma chemical vaporization machining was employed. High crystalline perfection of the fabricated Si(110) crystal was verified with X-ray topography and rocking curve measurements. In addition, the thickness was evaluated to be 4.4 μm from the fringe period of the measured rocking curve. The crystal can be employed in Bragg beam splitters using the (220) Bragg reflection for X-ray pump-X-ray probe experiments with XFEL sources.

A XUV Michelson interferometer has been developed by LIXAM/CEA/LCFIO and has been tested as a Fourier-transform spectrometer for measurement of X-ray laser line shape. The observed strong deformation of the interference fringes limited the interest of such an interferometer for plasma probing. Because the fringe deformation was coming from a distortion of the beam splitter (5 × 5 mm2open aperture, about 150 nm thick), several parameters of the multilayer deposition used for the beam splitter fabrication have been recently optimized. The flatness has been improved from 80 nm rms obtained by using the ion beam sputtering technique, to 20 nm rms by using the magnetron sputtering technique. Over 3 × 3 mm2, the beam splitter has a flatness better than 4 nm rms.

NPL x-ray gratings for use at grazing incidence in the wavelength range of 0.05 to 20 nm have diffraction efficiencies in the first order ranging from approximately 3% at 0.1 nm to 20% at wavelengths greater than 2 nm. X-ray gratings may have either a rectangular profile produced by processing a ruled or holographic grating or may have a shallow blazed waveform. In both types of grating, the grooves are formed in a vitreous silica blank and are usually overcoated with gold.A precision short wavelength (0.05 to 0.5 nm) Rowland circle focusing spectrometer has bee n constructed, which can cater for concave gratings of radii between 5 and 15 m.
