The development of intense and coherent electromagnetic sources offers novel pathways
in the search for new particles and exotic phenomena. A recently growing interest
is dedicated to the low mass particle candidates of Dark Matter.
We envisage the possibility of developing a multipurpose facility dedicated to the search of Axion-Like Particles, ALPs, based on the use of
Free Electron...

Channeling of low energy atomic particles in carbon naotubes is interesting for low energy ion implantation, local ion plasma enhanced deposition, chemicaly-biological and medical atomic particles transport application [1]. Carbon nanotubes sre useful as ion beam management system parts. Temperature variating along the nanotube production process allow us to variate CNT diameter, which creates...

In this report we present experimental investigation of interaction of the electromagnetic field of a relativistic bunched electron beam with a metamaterial. Used metamaterial target represents a right triangular prism. The unit cell of the target consists of a split-ring resonator (SRR) and a wire. The size of the unit cell is 3 mm. The measurements were done in millimeter wavelength range in...

Advanced computer technology and wide use of personal computers today open up great perspectives of computer simulations for studying various processes and phenomena of the surrounding world. Computer models are often used to obtain new data about simulated object or for approximate estimation of the system behaviour while this system is too complex for analytical exploration. Consistency of...

There are three fundamentally different mechanism of deflection of fast charged particle beam by a bent crystal. The first mechanism was proposed by E.A. Tsyganov [1], and is based on the phenomenon of planar channeling of charged particles in a bent crystal. The second, proposed by A.M. Taratin and S.A. Vorobiev [2], called the "volume reflection", is a single reflection of positive charged...

A high-brilliance ($>10^{20}$ phot.s$^{-1}$.mm$^{-2}$.mrd$^{-2}$/0.1%) gamma-ray source experiment is currently in preparation at Fermilab ($E_\gamma\simeq 1.1$~MeV). The source implements a high-repetition-rate inverse Compton scattering by colliding electron bunches formed in a 300-MeV superconducting linac with a high-intensity laser pulse. This contribution describes the design rationale...

The dynamics of relativistic particles is depended on the shape of the crystals and beam optics. The bending of the crystal is possible in many ways. One of the most powerful and natural way to find the needed bent is the using...

Electron acceleration using short pulse high power laser is one of the scheme proposed to reduce the size of the future accelerator.
Different scheme has been proposed to increase the acceleration length and the final electron energy, like use of gas filled capillary. Advance target design increases the demand on the quality of the laser beam, in particular to the pointing stability, that it...

We discuss the possibility to generate low emittance muon beams by colliding high energy hadrons and counterpropagating high brilliance photon pulses.
The asymmetric collision of Large Hadron Collider/Future Circular Collider like hadrons and FEL keV photons imparts a strong Lorentz boost to the secondary particles which are emitted at hundreds GeV energy within a small angle around the...

In order to gain control over hard X-ray (over 30 keV), X-ray diffraction in Laue geometry (over 30 keV) from a single crystal of quartz influenced by the temperature gradient has been considered. It has been experimentally proved that the intensity of the reflected beam can be increased up to several orders if the X-ray energies are 30 keV and 40 keV for reflecting atomic planes (10-11)...

The LAUPER project aims to demonstrate the feasibility of a Laue lens optimized to operate with X-rays emitted by a conventional X-ray tube to produce a focused photon beam for radiotherapy applications. In the context of tumor treatment, radiotherapy is an important method consisting in imparting a radiation dose to a target volume in order to destroy cancer cells. Any radiotherapy treatment...

Optical transition radiation (OTR) is widely used as a tool for transverse diagnostic of electron beams in many accelerator facilities around the world. It is generated when the beam of electrons intercepts a metallic or dielectric screen. The OTR then propagates in the direction of the mirror reflection to the point where it can be detected. Despite the fact that the electron beam can be...

In this work, we continue investigations of non-divergent radiation in volume and planar wire structures with small period. Unlike previous works, we consider the bunches moving along the semi-infinite planar wire structure. Besides, we consider not only thin bunches, but also bunches with finite cross-section.
We analyze surface waves generated by a charged-particle bunch at the...

Polycapillary optics is a well known technology used within different research and industrial fields. Generally these devices are applied for their integral properties, as flux gain factor, or for the micro- focus features useful for confocal geometry.
Less investigations have been spent about composition of the trasmitted beam.
In this work features about spot size, energy composition,...

Based on results of paper [1] devoted to study of volume reflection and volume capture we develope the so name "one-trajectory approximation of a diffusion process" for conditions of channeling process in straight and bent single crystals. We extend this approximation for a sufficiently long crystals. We also consider posively and negatively
charged hadron beams.

The analysis of experimental data obtained in the study of grazing interaction of fast electron beams with flat dielectric surfaces demonstrates a dependence of the surface charge distribution formation on the dielectric material. We found that the angular distribution of the electron beam does not depend strongly neither on the length of the surfaces nor on the beam current. In addition, the...

Nowadays X-ray absorption spectroscopy is widely used in the X-ray structural analysis [1] and can be applied to elemental analysis of substance [2]. A special group of absorption analysis methods imply measurements of the radiation absorption coefficients at a few energy lines that allow estimating a number of investigated object characteristics. Implementation of these methods requires X-ray...
