“…This feature has been further confirmed in references [26][27][28][29][30][31][32] within the framework of quasi-classical mechanics and electrodynamics. The consistent quantum theory for the influence of US on the ChR from electrons and positrons has been developed after 2000 and published in a series of papers, mostly by the IAPP employees [17][18][19][20][21][22][23][24][25]. Below we briefly discuss the results obtained in those works.…”

“…In figure 8 we show the spectral distribution of the intensity of the electron radiation for two transitions from the fixed initial state (full curve). [17,18,20] In [17] the solutions of the Dirac equation are derived for the positron with energy MeV 100 10   E , channeled in a single crystal stimulated by a longitudinal hypersonic wave, facilitating a resonant interaction between the hypersound and the positron. The research demonstrates that the overall intensity of the channeling radiation emitted by relativistic positron, interacting with the hypersonic field, results from various dominant radiative transitions.…”

“…As the wavelength s  of the hypersound decreases from , these inverse transitions exhibit a resonant behavior. Formulae describing the angular and spectral distributions of radiation intensity emitted by a planarchanneled positron under the influence of hypersound are presented in [18,20], (see equations (6.13a;b) and (6.23a;b) in [20]). Figure 11 displays spectral distributions of radiation intensity, illustrating transitions from the same initial state to various final states (see figure 10) [20].…”

One of the areas of research conducted at the Institute of Applied Problems of Physics (IAPP) is the study of the influence of different media on the radiation processes generated by relativistic charged particles (channeling radiation, transition radiation, Cherenkov radiation, diffraction radiation, etc.). Additionally, many interesting phenomena arise when acoustic fields are excited in media. This is exactly the field of study of acoustophysics. The paper is devoted to the review of studies conducted in Lab. 3 of IAPP in these areas.

Forward transition radiation is considered in an ultrasonic superlattice excited in a finite thickness plate under oblique incidence of relativistic electrons. We investigate the influence of acoustic waves on both the intensity and polarization of the radiation. In the quasiclassical approximation, formulas are derived for the vector potential of the electromagnetic field and for the spectral-angular distribution of the radiation intensity. It is shown that the acoustic waves generate new resonance peaks in the spectral and angular distributions. The heights and the location of the peaks can be controlled by choosing the parameters of the acoustic wave. The numerical examples are given for a plate of fused quartz.
