The possibility of using radiation of relativistic electrons in optical fibers using the properties of dielectric materials for diagnosing beams was theoretically suggested by the authors X. Artru and C. Ray. (Nucl. Instrum. Meth. B vol. 309 (2013). The aforementioned work studies the properties of various types of radiation induced in fibers by the electromagnetic field of relativistic electrons. In this paper, we present the experimental research of the influence of surface waves on the radiation propagating along a fiber. The work also investigates the properties of various types of coherent millimeter wave radiation that was induced in dielectric fibers by the electromagnetic field of relativistic electrons. The results also include the experimental analysis of nature and properties of coherent radiation in fibers, the analysis being performed for different positions of fiber in relation to the electron beam.

A strong electromagnetic field may modify the refractive index of the normal vacuum due to nonlinear effects caused by photon-photon interactions. In order to test the increase of the refractive index, Cherenkov radiations associated with relativistic electrons into the strong electromagnetic field can be utilized as an experimental probe. We will present a result of the experimental search for the Cherenkov emissions with a laser intensity of 1017W/cm2 with the wavelength of 800nm and the electron beam of 35.4MeV/c, where photons with kinematically expected Compton energies and a symptom of visible ray emissions were observed.

The formalism of form factors is the basis for the describing the coherent radiation of bunches that comprise relativistic charged particles. The general theory of coherent radiation for synchrotron and bremsstrahlung radiation, when radiation is generated directly by charged particles, but not by the material of a target, was developed long ago. However, there is no general model of coherent radiation for such polarization radiation as transition, diffraction and other types of radiation, when the radiation is generated by the material of a target polarized by the electromagnetic field of relativistic particles. This often causes the misapplication of the form factors of synchrotron radiation to other types of radiation. In this paper, we suggest the simplified algorithm for construction of form factors for different types of polarization radiation of relativistic electrons in the material of a target.
