Synchrotron radiation of electrons in inhomogeneous magnetic fields. The case of azimuthal inhomogeneity

The influence of induced oscillations on the characteristics of synchrotron radiation is considered. Formulas that are accurate to the first quantum correction are obtained for the intensity of components of the linear polarization of the radiation, taking account of both betatron and induced oscillations of the electron beam. It is noted that distortion of the magnetic median surface must be taken into account in experiments with synchrotron radiation.
