In 1990s, the emergence of the 3rd generation synchrotron user facilities equipped with undulator sources, stimulated pioneering works on interaction of coherent X-ray beams with matter (Brauer et al. 1995), resulted in the development of X-ray photon correlation spectroscopy (XPCS) technique, capable to probe nanoscale fluctuations up to kHz frequencies using dynamics of speckle pattern given...
The design of the user station for a fourth-generation synchrotron radiation (SR) source SRF “SKIF” has been proposed. The station is designed to solve a wide range of research and technological tasks using X-ray diffraction techniques. The concept of the station is based on the implementation of a complex approach to the structural studies of synthetic and natural objects. The most complete...
“Fast Processes” is one out of six 1st priority beamlines that are planned for construction within the project SRF SKIF (Shared Research Facility “Siberian circular photon source") [1]. The beamline would include two independent instruments installed at a wiggler source, i.e., Dynamic processes and Plasma. The beamline is designed to meet a wide range of research and technological challenges...
Selective laser melting is an additive technology that is gaining popularity due to its ability to produce complex metal components that cannot be manufactured using traditional technologies.To achieve high quality components created using SLM, it is necessary to control the processes of melting and subsequent crystallization in metals. Using the high synchrotron radiation (SR) intensity from...
“Electronic Structure” is a state-of-the-art beamline for methods using the Soft X-Rays range (10-2000 eV) at the 3 GeV ring of SKIF synchrotron facility. At present, three branch lines is funded, which will host an end station for Near Ambient pressure X-Ray Photoelectron Spectroscopy (NAP XPS), Spin-Angle Resolved Photo-Emission Spectroscopy (Spin-ARPES) and Reflectometry and Metrology. The...
The most advanced X-ray sources, such as third-generation synchrotrons and free electron lasers (XFEL), are capable to generate high brightness coherent radiation, especially in the hard X-ray region. The availability of such beams facilitates the development of a new generation of X-ray optics, whose optical properties allow going far beyond simple collimation and focusing functions. This...
Different kinds of X-ray mirrors are required for beam alignment, guidance or monochromator applications. Therefore various types of optics with coatings for energy ranges between 100 eV and 80 keV have been investigated.
We will show stripe multilayer coatings which are often used as Double Crystal Multilayer Monochromators (DCMM) for example in tomography beamlines. The optics consists of...
Optical systems based on compound refractive lenses (CRLs) with rotationally parabolic profile [1] are amongst the most advanced optical components at the novel synchrotrons worldwide [2]. Methods and technologies of their production one of the most rapidly progressing areas of modern synchrotron instrumentation techniques. Manufacturing of CRLs is closely related to the analysis of...
The visualization and analysis of 3D fields of elastic displacements of micro-dimensional defects and dislocation structures in the volume of single crystals are important in the development of new functional materials. For this purpose, the X-ray diffraction tomography (XRDT) method is increasingly being used. We use XRDT to study the real structure of different single crystals, in...
We have employed VEPP-4 synchrotron radiation to measure CCD detector absolute responsivity in vacuum ultraviolet (115-310 nm) spectral range. The detector is designed in the form of a stainless steel enclosure containing a backside-illuminated CCD to protect the CCD from contamination. The entrance window of the enclosure is a round MgF2 spectral filter transparent for ultraviolet radiation...
This work considers the optical properties and structure of thin films of titanium dioxide formed by glancing angle deposition to improve light yield of scintillation materials. The experimentally obtained value of the refractive index was about 1.2, which is almost two times less than the refractive index of crystalline titanium dioxide. This allows you to use this method to modify the...
