Resonant amplification of a relativistic electron bremsstrahlung on an atom in the undulator field

TL;DR

This paper demonstrates that an undulator field can resonantly amplify relativistic electron bremsstrahlung on atoms, significantly increasing the bremsstrahlung cross section near the radiation spectrum's end, making experimental observation feasible.

Contribution

It introduces the concept of resonant amplification of bremsstrahlung due to undulator fields, highlighting a new way to enhance radiation processes in atomic interactions.

Findings

Bremsstrahlung cross section is significantly increased near the spectrum's end.

The effect is observable with current experimental setups.

Undulator fields can be used to control and enhance electron radiation processes.

Abstract

It is shown that the influence of the undulator field on the motion of a relativistic electron leads to a significant increase of the bremsstrahlung cross section on an atom near the end of the spectrum of undulator radiation. Observation of this effect is quite a realistic task.
