“…This direction is at large angle from the electron beam, thus eliminating the bremsstrahlung background. PXR does not come alone, but is accompanied by Diffracted Transition Radiation (DTR) [14][15][16] : transition radiation produced at the entrance surface of the crystal also undergoes Bragg diffraction. PXR and DTR are have similar shapes and usually interfere.…”

The amplitude of Parametric X-ray radiation emitted coherently by a bunch of electrons crossing a crystal (CPXR) is calculated. When the bunch density is modulated with a longitudinal period close to the X-ray wavelenght, constructive many-electron interferences enhance the intensity by N b × |F (K)| 2 , where N b is the number of electrons in the bunch, F (K) the bunch form factor and K a specified wave vector. CPXR can be used to test the microbunching in a X-ray free-electron laser.

The radiation emitted by a charged particle moving along a helical orbit inside a dielectric cylinder immersed into a homogeneous medium is investigated. Expressions are derived for the electromagnetic potentials, electric and magnetic fields, and for the spectral-angular distribution of radiation in the exterior medium. It is shown that under the Cherenkov condition for dielectric permittivity of the cylinder and the velocity of the particle image on the cylinder surface, strong narrow peaks are present in the angular distribution for the number of radiated quanta. At these peaks the radiated energy exceeds the corresponding quantity for a homogeneous medium by some orders of magnitude. The results of numerical calculations for the angular distribution of radiated quanta are presented and they are compared with the corresponding quantities for radiation in a homogeneous medium. The special case of relativistic charged particle motion along the direction of the cylinder axis with non-relativistic transverse velocity (helical undulator) is considered in detail. Various regimes for the undulator parameter are discussed. It is shown that the presence of the cylinder can increase essentially the radiation intensity.

“…(5) is identical to the one of a similar expression for resonant transition radiation from N layers, taking into account the radiation absorption in every layer [7]. First of all, a particular case will be considered which corresponds to the conventional Smith-Purcell geometry (H 0 = 0).…”
