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.
