Introduction
Since 2018, we have been involved in R&D on X-ray mirror metrology and fabrication technologies. After five years of intense R&D efforts, we successfully integrated ion beam figuring (IBF) with advanced metrology, as seen in Fig. 1, demonstrating diffraction-limited hard X-ray mirror manufacturing capability (curved surfaces with up to a 0.6 mrad total slope) [1]. We have...
High-energy x-ray (40-140 keV) optics development at the Advanced Photon Source (APS) will be presented, encompassing monochromatization (for high-heat-load and high-resolution applications), focusing (with refractive optics such as tunable saw-tooth lenses and kinoforms), and full-field imaging. In addition to the experimental capabilities already enabled by these optics, such as various...
At the European XFEL, two-color pump-probe experiments offer crucial insights into chemical reactions and molecular dynamics. High-intensity X-ray pulses with extremely high repetition rates enable researchers to observe sequential ionization. By adjusting the time delay between pump and probe pulses and tuning their wavelengths, researchers capture the sequence of events. To achieve this an...

The progressive development of X-ray laser sources requires high stability of optics that are distributed over large distances. X-ray laser amplifiers, which rely on the coherent superposition of circulating micron sized, femtosecond x-ray pulses in cavities, place demands on length and angular stability in the 100s nanometer and nanoradian range. They also need to interact with the gain...
The compound refractive lens (CRL) made of single crystalline diamond material for focusing X-ray beam at synchrotron radiation and X-ray free electron laser (XFEL), especially high power and high photon energy sources, has become a promotive topic during the last decade. Plenty of advantages such as non-toxic, higher refractive power, mechanical and radiation hardness, thermal conductivity,...
Undulators serve as the primary magnetic structures for generating synchrotron radiation in third and fourth-generation sources. The emitted radiation from undulators is intricate, featuring spectrum peaks at specific photon energies (resonances), and the
beam geometry is notably influenced by the photon wavefront and emittance of the storage ring. Various software tools exist for assessing...
