Grazing incidence at work: an outreach project to demonstrate the X-ray optics behaviour using the nested mirrors developed for the BeppoSAX X-ray satellite [PDF]

, 2019
BeppoSAX was an Italian-Dutch satellite designed for X-ray observations, launched in 1996 and deactivated in 2002. It was the first satellite to precisely localize the Gamma Ray Bursts and to detect the X-ray emission due to the afterglow, a breakthrough

Precision motion control of X-ray optics assisted with optical interferometric metrology for advanced X-ray beam sources

Light: Advanced Manufacturing
Nanoradian precision has been achieved in control of X-ray optics using feedback from optical interferometric measurements and real time adjustments of three mirrors in a simulated X-ray laser cavity in recent work reported by Koehlenbeck et al.

Dynamics of the Bloch point in an asymmetric permalloy disk

Nature Communications, 2019
The intrinsic nature and dynamics of a Bloch point has not been verified so far. Here, Im et al. report the realization and dynamical character of steady-state Bloch points in the magnetic vortex cores in asymmetrically shaped Ni80Fe20 nanodisks.
