Abstract: A new source of electromagnetic radiation in a wide spectral range can be based on multiple contactless deflection of the beams of charged particles in a circular channel. The radiation with wavelengths ranging from submillimeter to radio ranges can be generated using nonrelativistic electrons. Directional radiation is obtained at relativistic energies. The IR, optical, and UV radiation can be generated. The X-ray and gamma-radiation can be obtained at relatively high energies. The new source is compared with the source of synchrotron radiation. The radiation intensity at energies of 1–2 GeV is relatively high, since strong currents are possible in the ring channel. The channeling and synchrotron emission are simultaneously obtained at relatively small (several tens of nanometers) internal diameters of the ring.
