Peculiarities of Bremsstrahlung of Cherenkov electrons

We investigated theoretically the peculiarities of Bremsstrahlung produced by decelerated Cherenkov electrons. We calculated the form of the wave fronts and the structure of the radiation using Lienard-Wiechert potentials. Significantly found peculiarities of the radiation structure were compared to the case of rectilinear motion considered by I. Tamm and I. Frank. In particular, we found that a significant longitudinal component appeared because of the deceleration of the charge. We found that for some parameters of the electron motion, the electrical field changes its direction for a short time during deceleration.
