“…This technique is based on the use of a Cherenkov radiation generated by the charged particle bunch moving through the waveguide [1,2]. In this connection, the possibility to use rectangular [3][4][5] and cylindrical [6,7] waveguides containing a vacuum channel as an accelerating structure is considered. Analysis of the wakefield formation process is significant for this acceleration method.…”

We consider the electromagnetic field of a point charged particle moving along the axis of a cylindrical waveguide from a homogeneously filled area to a dielectric loading area having an axially symmetrical channel. We are interested in studying the Cherenkov radiation excited in the bilayer area. The solution is performed by expanding the field in each area in a series of orthogonal eigenmodes. The main attention is focused on investigation of the wave field in the bilayer section. We show that, at a given observation point, the "reduced wakefield" is simplified with time (the number of modes decreases). The obtained results are generalized for the case of a bunch with Gaussian longitudinal profile. The typical numerical results for wakefield formation process are presented. These results agree with simulations done by the industry standard electromagnetic code CST Particle Studio.

“…The above equations (4)-(7) illustrate a common near-field-far-field transformation algorithm [7]. If the distribution on the plane is axially symmetric (depends only on the distance r ¼ ffiffiffiffiffiffiffiffiffiffiffiffiffiffi ffi x 2 þ y 2 p from the center point of the plane) and is nonzero only within the aperture, the expressions (5) and 7are simplified and can be represented as follows:…”

“…Recently, a new traveling wave structure has been proposed [1]: an internally coated metallic pipe (ICMP), which has only a single slowly propagating (phase velocity is equal to the velocity of light) TM 01 mode. Because of an absence of the high slowly propagating modes, the above structure could be effectively used for particle acceleration or generation of monochromatic radiation [2][3][4][5]. The experimental study of an ICMP type structure is currently under development at AREAL test facility [6].…”

In this paper the problem of radiation from the open end of a semi-infinite circular metallic waveguide with perfectly conducting walls and a thin internal low-conducting metal coating is considered. Electromagnetic fields are generated by the ultrarelativistic point charge moving along the axis of the waveguide. The far fields of radiation are obtained using the near-field to far-field recovery technique. The technique is extended for the nonmonochromatic waves. It is shown that the radiation has a narrow-band and narrow-directional character.
