X-ray free electron laser (XFEL) can generate ultrashort X-ray pulses with extremely high intensities [1,2]. The XFEL pulses are manipulated by X-ray optics in the beamline, such as focusing, collimation, compression, and monochromatization, before being transported to the experimental endstati...
based on geometric optics applied on both the objective lens and the microlens array. In this approach, the ray propagation is given as a function of the physical distances of the setup, without assuming a specific configuration or any relationship between the distances and the parameters. It is...
Versions Notes Abstract In a recent work (Antonov et al., Physical Review Letters 123, 243903 (2019)), it was shown that it is possible to amplify a train of attosecond pulses, which are produced from the radiation of high harmonics of the infrared field of the fundamental frequency, in ...

Versions Notes Abstract This work aims to evaluate the application of optical and X-ray spectroscopy methods to determine the effect of alpha-emitting radionuclides on the properties of solid-state nuclear track detectors (SSNTD) based on nitrocellulose during their detection. The proposed estimation ...
Versions Notes Abstract If ancient documents are too fragile to be opened, X-ray imaging can be used to recover the content non-destructively. As an extension to conventional attenuation imaging, dark-field imaging provides access to microscopic structural object information, which can be especially ...
