Effects of Transverse Periodic Perturbation on Channeling Radiation

摘要

When a transverse periodic perturbation of amplitude much larger than the interplanar spacing is propagating through a single crystal, the crystal is bent periodically which results in the emission of undulator radiation in addition to channeling radiation from the channeled particles. When the amplitude is small compared to the interplanar spacing, undulator radiation contribution is negligible in the spectrum. In this work, we are considering the propagation of a low amplitude periodic perturbation. The angular and spectral distribution of emitted radiation is calculated and the corresponding intensity is estimated.
