Abstract: The Vavilov–Cherenkov radiation generated by a relativistic electron bunch that propagates in the vacuum channel of a rectangular dielectric-filled wakefield accelerating structure is analytically described. The approach is based on the expansion of wake fields in terms of the eigenfunctions of operators of the transverse electric and magnetic field components. Expressions for the wake fields generated by a Gaussian electron bunch are obtained. Using the proposed formalism, parameters of a diamond-based accelerating structure admitting the generation of potential gradients above 100 MV/m have been calculated for a typical electron bunch of the Argonne Wakefield Accelerator.
