The phenomena of spin rotation and depolarization of high-energy particles in crystals in the range of high energies that will be available at Future Circular Collider (FCC) can be used to measure the anomalous magnetic moments of short-lived particles. We demonstrate that the phenomenon of particle spin depolarization in crystals provides a unique possibility of measuring the anomalous...

Thermal vibrations of neighboring atoms are correlated : long wavelength phonons make them displace in the same direction. For channeled particle the correlated displacements make dechanneling faster. For channeled electrons or positrons, it increases the coherence of bremsstrahlung over consecutive atoms, making a kind of semi-coherent contribution to bremsstrahlung . These effects are...

A new diffusion equation is suggested to correctly describe the channeling particle diffusion in transverse energy, taking into consideration the contribution of both the fourth power of incoherent scattering angle to the transverse energy dispersion and the catastrophic dechanneling effect, caused by the large-angle single incoherent scattering. This equation is reduced to the Sturm-Liouville...

Spectral features of proton channeling radiation, revealed by the interference of two modes of circular waves with the same frequency and amplitude, are studied.
The beam modulation is resolved using the realistic Monte Carlo simulation by taking into account the degree of spatial coherence and longitudinal coherence length, multiple scattering effect, electron energy loss, emission angles,...

Oral presentation
At motion of accelerated charged particle through crystal the phenomenon of plane channeling is possible, at which the particle performs oscillatory motion in the channel formed by crystal planes. In ultrathin crystals such regime fails to be established, and a problem appears on the properties of motion and scattering of particles in this case. For MeV electrons such a transitional motion...

This work presents continuation of experimental and theoretical studies of the scattering of 255 MeV electrons by aligned crystals at SAGA-LS accelerator facility. In the previous series of experiments we studied the doughnut scattering (DS) [1], scattering at planar alignment (SPA) [2] and mirroring [3-5]. The advantage of these studies is the fixed electron beam energy and different crystal...
