Perfect X-ray focusing via fitting corrective glasses to aberrated optics

Nature Communications, 2017
X-ray optics are notoriously challenging to fabricate due to the strict tolerances that result from the short wavelength of radiation. Here, Seibothet al.

Characterization of silicon pore optics for the NewAthena X-ray observatory in the PTB laboratory at BESSY II

Journal of Synchrotron Radiation
The New Advanced Telescope for High ENergy Astrophysics (NewAthena) will be the largest space-based X-ray observatory ever built. It will have an effective area above 1.1 m2 at 1 keV, which corresponds to a polished mirror surface of about 300 m2 due to ...

Lobster-Eye All-Sky Soft X-ray Monitors [PDF]

, 2015
The idea of a satellite providing monitoring of specified sky areas in soft X-rays is presented. Observation plan could include also e.g. searching for X-ray afterglows of gamma-ray bursts. The spacecraft could be of the nano-satellite class.

Aberration correction for hard x-ray focusing at the nanoscale

, 2017
We developed a corrective phase plate that enables the correction of residual aberration in reflective, diffractive, and refractive X-ray optics. The principle is demonstrated on a stack of beryllium compound refractive lenses with a numerical aperture ...

Development of an x-ray excited optical luminescence microscope (XEOM) [PDF]

X-ray excited optical luminescence (XEOL) refers to the trans-visible emission produced as a consequence of X-ray bombardment and provides an alternative detection method for X-ray absorption spectroscopy (XAS). Whereas XAS measured by conventional means
