Ultrathin monolithic bimorph mirror using polarization-inverted lithium niobate wafer [PDF]

Scientific Reports
Deformable mirrors (DMs) serve diverse applications and have been adopted in X-ray optics recently. DMs are being used in various X-ray optical systems with variable parameters, with piezoelectric bimorph mirrors favored the most.

Automated alignment of XFEL nanofocusing mirrors via wavefront optimization [PDF]

Journal of Synchrotron Radiation
An automated alignment procedure, based on wavefront measurement with a single-grating interferometer, has been developed for precise tuning of Kirkpatrick–Baez nanofocusing mirrors for X-ray free-electron lasers (XFELs).

Characterization of a lobster-eye type X-ray telescope [PDF]

EPJ Web of Conferences, 2022
Lobster-eye type X-ray telescopes use reflecting plano mirrors under grazing incidence and can observe a large field of view. As part of a Bavarian-Czech cooperation, two telescopes were build, equipped with mirrors coated with gold and iridium.

One-dimensional image scaling with a reflecting X-ray mask

Vìsnik Harkìvsʹkogo nacìonalʹnogo unìversitetu ìmenì V.N. Karazìna. Serìâ: fìzika., 2022
The work deals with the issue of miniaturization of template images using X-ray radiation. The compression method is based on the fact that X-ray radiation is directed at a specific template that reflects X-ray radiation at an grazing angle and a one ...

The development of the mirror for the Athena X-ray mission

International Conference on Space Optics — ICSO 2022, 2023
Athena is the European Space Agency's next flagship telescope, scheduled for launch in the 2030s. Its 2.5 m diameter mirror will be segmented and comprise more than 600 individual Silicon Pore Optics (SPO) mirror modules. Arranged in concentric annuli and following a Wolter-Schwartzschild design, the mirror modules are made of several tens of grazing ...

Study of interface reaction in a B4C/Cr mirror at elevated temperature using soft X-ray reflectivity

Journal of Synchrotron Radiation, 2022
Boron carbide is a prominent material for high-brilliance synchrotron optics as it remains stable up to very high temperatures. The present study shows a significant change taking place at 550°C in the buried interface region formed between the Cr ...

X-Ray Single-Grating Interferometry for Wavefront Measurement and Correction of Hard X-Ray Nanofocusing Mirrors

Sensors, 2020
X-ray single-grating interferometry was applied to conduct accurate wavefront corrections for hard X-ray nanofocusing mirrors. Systematic errors in the interferometer, originating from a grating, a detector, and alignment errors of the components, were ...

The development of the mirror for the Athena X-ray mission

Space Telescopes and Instrumentation 2022: Ultraviolet to Gamma Ray, 2022
Athena is the European Space Agency's next flagship x-ray telescope, scheduled for launch in the 2030s. Its 2.5-m diameter mirror will be segmented and comprise more than 600 individual Silicon Pore Optics (SPO) grazing-incidence-angle imagers, called mirror modules. Arranged in concentric annuli and following a Wolter-Schwartzschild design, the mirror
