Journal of Synchrotron Radiation. 25:407-412
Precise monitoring of the incoming photon flux is crucial for many experiments using synchrotron radiation. For photon energies above a few keV, thin semiconductor photodiodes can be operated in transmission for this purpose. Diamond is a particularl

We present the expected coating performance based on design and simulations, tested coating performance evaluated by means of X-ray reflectometry and short and long term stability of several materials considered as coating options for the X-ray mirro

Optics for EUV, X-Ray, and Gamma-Ray Astronomy VIII.
While predictions based on the metrology (local slope errors and detailed geometrical details) play an essential role in controlling the development of the manufacturing processes, X-ray characterization remains the ultimate indication of the actual

We report the latest results on coating design optimisation and optics performance for the present Ir/B4C baseline coating and alternative designs and materials, including bilayers and linear graded multilayers. We make use of X-ray reflectometry (XR
