Summary:	Title screen The article presents the results of an experimental study on the spectral modes of coherent Cherenkov diffraction radiation in the sub-terahertz frequency range. A long cylindrical Teflon radiator was used as a target. The Advanced Research Electron Accelerator Laboratory linear accelerator, located at the Center for the Advancement of Natural Discoveries using Light Emission Synchrotron Research Institute in Yerevan, has been used as a source of electrons with the energy of 3.6 MeV. The radiation was analysed with Martin-Pupplett interferometer and recorded using full band Schottky barrier diode detectors, designed for frequency bands Q: 33–50 GHz, E: 60–90 GHz, and F: 90–140 GHz. The obtained results are compared with theoretical calculations and demonstrated a good consistency. Cherenkov diffraction radiation offers considerable potential for the development of intense photon sources in the THz and sub-THz frequency ranges, as well as for applications in particle beam diagnostics Текстовый файл AM_Agreement
