Thomson/Compton scattering is well-known as a scattering process between electromagnetic radiation and charged particles, which is found in laboratories and nature. Here, we investigate the radiative properties of nonlinear Thomson scattering with arbitrary incident angle. Based on classical electrodynamics, the analytical universal expressions of the electric field and energy spectrum of the...

The processes of interaction of charged particles in crystals at channeling are well studied today. Based on the physics of channeling in crystals, new methods are being developed for controlling beams of both charged and neutral particles. However, in addition to the innovative tool of controlling particle beams through channeling, it is well known that the effect of channeling of charged...

One of the devices for generating circularly polarized radiation of high frequency is a helical undulator in which a relativistic charged particle moves along a helical trajectory. In this paper, the spatial distribution of the electromagnetic field produced by such a particle is analyzed using electric field lines. The equations of electric field lines, which, due to the presence of curvature...

The noncentrosymmetric optical borates are promising materials for modern high-power laser systems because of high nonlinear optical (NLO) coefficients, wide transparency windows including visible and UV ranges, and high optical damage thresholds, etc. One of such borates is SrB4O7 (SBO). Large single crystals of SBO with high optical qualities were grown by the Kyropolus method [1]. SBO has...

During the last decade Lead Halide Perovskites (LHPs) have been widely researched in the photovoltaic and light emission fields due to their outstanding optoelectronic properties and exceptional performance. Owing to their low cost and easy fabrication, tremendous achievements were achieved in solar cell, photodetector, light‐emitting diode and laser research fields.

The possibility of using ordered three-dimensional arrays of photonic crystals to generate gigahertz, optical, and neutron radiation during the interaction with them a beam of high-energy electrons is considered. Experiments were carried out to record two-dimensional images of objects in gamma and neutron fluxes obtained as a result of the interaction of an electron beam with various...

In the framework of the report we discuss the description problem of a diffracted plane wave incident on system of randomly and in average periodically located scatterers. We suggest that the scatterers under the action of the prime field are appeared as sources of secondary sphere waves. The problem is considered in the Fraunhofer approximation.

Quasars are perhaps the brightest extragalactic sources, and due to their brightness, they are visible at greater distances. By studying the distribution of quasars in the Universe, it is possible to determine whether there are large-scale inhomogeneities in the Universe or not. If the distribution of quasars is inhomogeneous at large distances, then the same can be stated about the Universe....

Vladislav SyshchenkoGeneral Properties of Radiation from Relativistic ParticlesOral
The positively charged particles can perform the axial channeling in the small potential well formed between four neighboring [100] strings of the Silicon crystal. The transverse motion of the particle in this well can be both regular and chaotic, and the relative volume in the phase space filled by the regular trajectories decreases while rising from the bottom of the potential well to its...

The character of motion (regular or chaotic) on the quantum level manifests itself in the statistics of the set of the system’s energy levels. The complete regular case generates the sequence of the levels with exponential (Poisson) level spacing distribution; the complete chaotic case generates one with Wigner distribution [1]. The most interesting case is the co-existence of the regular and...

Understanding the intricate interactions between ionizing radiation, electron beams, and biological systems is essential in elucidating the mechanisms behind radiation-induced damage to DNA structure. Fast electrons directly ionize DNA molecules, leading to various forms of damage such as single-strand and double-strand breaks. Combining porphyrin-based Photodynamic Therapy (PDT) with electron...
