The narrow-band resonance in two-layer metallic round tube
The regularities of narrow-band resonance in a two-layer circular waveguide due to the radiation of the bunch, moving along its axis are investigated. Its connection with the synchronous component of a two-layer TM01 mode of the waveguide is established. Also performed numerical and analytical calculations of wake functions (particle radiation fields) and are investigated its properties. The possibility of using a two-layer waveguide as a powerful source of quasi-monochromatic terahertz radiation and as an efficient device for the two-beam acceleration is shown. Preliminary experimental scheme is proposed.
