Observation of coherent transition radiation
Physical Review Letters, 1991Coherent transition radiation, generated by the passage of mm-long bunches of electrons through a thin metal foil, has been observed in the far infrared. The intensity was compared to the smaller amount of Cherenkov radiation produced when ${\mathrm{SF}}_{6}$ gas was introduced into the electron path.

On microwave transition radiation
Technical Physics, 1998The energy of the radiation emitted by an ultrarelativistic (1 GeV) electron at a transition from vacuum into yttrium iron garnet I3Fe5O12 at the ferromagnetic resonance frequency (vacuum wavelength 3 cm) is estimated. The energy at this frequency was found to be 10−13 eV·s.

Abstract Transition radiation has been revisited to rectify some inconsistencies in the original Ginzburg and Frank formulation. Our calcualtions of radiation intensity exhibit qualitative deviations from the original formula, particularly in the nonrelativistic limit.

Transition radiation of multicharged ions
Journal of Experimental and Theoretical Physics, 2015The problem of the transition radiation of multicharged ions at the interface between two media and in a thin plate under the charge-exchange conditions has been solved. It has been shown that the processes of pickup (or loss) of electrons by accelerated multicharged ions at the interface between two media significantly increases the yield of ...

1998
Publisher Summary The chapter presents a study on transition radiation. When an energetic charged particle makes a transition from vacuum into a metal, there is an emission of electromagnetic radiation known as “transition radiation.” This radiation appears whenever a charged particle crosses an interface separating media of different dielectric ...

Transition radiation in an elastic wheel
Journal of Applied Mechanics and Technical Physics, 1995The goal of the article under review is to qualitatively study the phenomenon of transition radiation in an isolated elastic system (wheel). The wheel is simulated as a wire expanded with springs, the stiffness of which is uniformly distributed with respect to the angle.

As it follows from the figure, the minimal value of the TR yield coincides with a direction of charge velocity. The angular distributions of TR for various values of the Lorentz-factor (and accordingly β) in dependence of the direction cosines, which can change from −1 up to +1 are shown in the presented figure.

Transition radiation and Bragg resonances
Physical Review A, 1994Both spontaneous and stimulated radiation emitted by an electron beam traversing a periodic medium are studied in the approximation of neglecting the influence of the field on the motion of the electrons. The results are valid both in the vicinity of the Bragg domain as well as far from it.

17th International Conference on Infrared and Millimeter Waves, 2017
We have obtained a new kind of light source, coherent transition radiation, using linear accel- erators and have examined its properties. It will be useful for IR and MM wave spectroscopy owing to its continuous spectrum and its picosecond duration. It will also be useful for analysis of a bunch shape of charged particles.
