Features of polarized monochromatic Cherenkov radiation in the UV, optical and terahertz range

The spectral-angular characteristics of polarized Cherenkov radiation of relativistic particles in quartz glass are analyzed in the ultraviolet, optical and terahertz spectral ranges at grazing angles of entry into the target. The radiation generated in thin quartz targets can be used both for creating monochromatic directional radiation sources in various spectral ranges and for diagnosing the angular characteristics of beams of accelerated relativistic particles.
