“…The e + e − pair production has been also observed. The strong-field QED effects like channeling radiation and e + e − pair production at the interaction of relativistic electron beam with crystalline fields has been also studied experimentally and theoretically [11,12]. A number of theoretical and numerical models for QED effects accompanying an interaction of relativistic electrons with strong electromagnetic fields has been developed.…”

Electromagnetic cascades attract a lot of attention as an important QED effect that will reveal itself in various electromagnetic field configurations at ultrahigh intensities. We study cascade dynamics in rotating electric field analytically and numerically. The kinetic equations for the electronpositron plasma and gamma-quanta are formulated. The scaling laws are derived and analyzed. For the cascades arising far above the threshold the dependence of the cascade parameters on the field frequency is derived. The spectra of high-energy cascade particles are calculated. The analytical results are verified by numerical simulations.

“…In addition, the geometry of the solutions, the impuriton-phonons, is similar to motion of a channeling particle [35]. Apparently, the impuriton-phonons as well as the channeling particles more easily move in less densely packed planes in less densely packed areas, between the crystal planes.…”

The properties of quantum solid solutions are investigated theoretically taking into account the interaction between waves of different nature: phonons and impuritons. The wave's interaction leads to a nonlinear Schrodinger equation that describes soliton -the impuriton-phonon, a new quasiparticle. As shown, the impuriton-phonons have velocity comparable to sound speed. Under heat step at the inclusion-matrix boundary a chemical potential step is formed. This leads to transition of 3 He atoms into the matrix with one of the following mechanisms: (i) phonon emission and band movement of the impuriton; (ii) threshold emission of the impuriton-phonon (the photoelectric effect analogy). It is shown that the narrow impuriton band cannot describe the rapid movement of the impuriton-phonon quasiparticle; alternative descriptions, channeling and induced transformation of the band, are proposed. It qualitatively explains the experiments with rapid dissolution of the 3 He phase inclusion in the 4 He matrix.

“…Since for an ultra-relativistic particle L d ∝ ε [18][19][20], it seems natural that to increase N d one can consider higher energies. However, at higher energies another limitation appears [2,3,6].…”

Abstract. We discuss the features of a crystalline undulator of the novel type based on the effect of a planar channeling of ultra-relativistic electrons in a periodically bent crystals. It is demonstrated that an electron-based undulator is feasible in the tens of GeV range of the beam energies, which is noticeably higher than the energy interval allowed in a positron-based undulator. Numerical analysis of the main parameters of the undulator as well as the characteristics of the emitted undulator radiation is carried out for 20 and 50 GeV electrons channeling in diamond and silicon crystals along the (111) crystallographic planes.
